There are two major open source social networking platforms that are garnering much attention of late: BuddyPress and Elgg. Elgg 1.0 was released in August 2008. BuddyPress is currently in beta. Regular visitors to this blog have probably read many of my posts on Elgg. Recently, I posted some first impressions of BuddyPress as a user having created an account on BuddyPress’s test site.
I just finished a BuddyPress installation on my server, so I am now able to make more comparisons between the two platforms. The intent of this is not so much to decide which platform is superior, but to discuss the features, interfaces, and administration of each; thus, helping individuals decide which may be best suited for their purposes. Having looked both over, I believe that each may be best suited for different purposes.
Installation
Both Elgg and BuddyPress require the administrator to set up a mySQL database. The packages must be uploaded to a web server, and browser based installers are used to attach the database to the software and create the appropriate config files to make the programs work. They also require Mod Rewrite to be enabled on the server. Beyond that, there are several differences.
BuddyPress installation is fairly complex. First WordPressMu must be installed which is simply a matter of creating a database, uploading the software, and running the installer. (One caveat: WPMU is much easier to install in the root public_html directory.) The only thing out of the ordinary is the option to use subdomains (blog.mysite.com) 0r subdirectories (mysite.com/blog). The former is generally recommended and requires activating wildcard dns on your server. Next you need to ftp and install the BuddyPress plugins and themes to the appropriate directories.
Finally, one needs to install and integrate bbPress if one wants the forums to function. bbPress must be uploaded and it should share a database with WPMU. It took a lot of back and forth with the admin interfaces and tweaking the bbPress and WPMU config files to make the cookies work.
Elgg installation is very straight forward. The Elgg developers responded to early complaints about difficulties with installation and made it even less particular about server configuration. Create a database, upload the software, run the installer. It doesn’t matter whether it is installed in the root or a subdirectory.
Now this might sound like a slam dunk for Elgg, but the results of installation are not equal. Let’s start by looking at the front page. The resultant buddyPress looks like this:

BuddyPress presents the admin with a prompt to add widgets to the threee columns on the front page. Click on the add widget link and you arrive at a familiar WordPress Widget interface.

The front page is easily customized by adding widgets to the three columns and arraying them as desired. Elgg, on the other hand, has a front page that is initially simple and much more difficult to customize.

Customization of the front page is done using plugins (or hacking the core) which must be hand coded to render the desired results.
Default Features
Another area worth comparing is the default features with a standard installation of each package.

The chart is really a rather superficial treatment, but serves to demonstrate that the two packages have similar feature sets. In spite of the similar set of tools, these tools are substantially different in many cases. Comparing these individual features will the subject of future blog posts.
Both Elgg and BuddyPress both require hand coding to create a good social networking plaform. BuddyPress currently requires a certain amount of coding in the installation process; whereas, Elgg requires coding to create something other than the spartan default main page. They have similar features, but the implementation is substantially different. Further comparision of components will yield more insight into the differences between the two platforms. In addition, the user and administrative interfaces represent other points of departure. Look for more posts comparing these two platforms in the near future.

CommentPress
February 24, 2009 in open source, Social Networking, Technology, wordpress | 5 comments
I recently came across CommentPress. It’s a WordPress plugin that allows readers to comment on a post paragraph by paragraph. CommentPress looks like a very promising collaboration tool. CommentPress is on the cusp of a major upgrade from version 1.4.1 to 2.0. We will look at features in the current version, and preview Version 2.0.
Currently, CommentPress is a WP theme. Install it and activate it.
The resultant main page includes a table of contents on the left side, a “page” that you can customize in the center, and some widgets on the right. The meat of this comes when you clink a link to one of the posts.
Each paragraph has a “speech bubble” to the right of it. Click on that and you can view all the other comments on that paragraph. Comments can even be threaded. Whether or not there are comments already, there is a text field for entering comments.
As it stands, CommentPress works well. Yet the developers plan on giving it even greater flexibility with version 2.0 due out in a couple weeks. I had trouble with the beta on my server, so I can only write about what I have seen and read on their site.
Rather than just a theme, the new version will include 3 plugins and a theme that can work independently so you only use the components you need. You will be able to use it with most WordPress themes. The comment box can be dragged and dropped to any location on the page. There are also enhancements that improve CommentPress’s ability to work with changed text in the posts. I also understand that it will be more flexible in working with other widgets and plugins.
CommentPress’s potential in education and in other areas is great. The ability to annotate and critique text paragraph by paragraph make it much easier to focus a response to a given segment of text. It would work well for peer editing of student writing. Teachers could post a segment of text for students to read allowing them to respond to the text and other comments. I have installed CommentPress to facilitate discussion of our school’s web publishing policy.
I look forward to working with a new version of CommentPress, but I wouldn’t hesitate to recommend it as it is today. As a bonus, the current version works with WPMU, and I hope the newer version will as well.
