I had someone ask me this question the other day...I have been looking for a good DotNetNuke blog module, and have tested the core DNN Blog module project, and have yet to find one that really has all of the features and functionality I need.
The requirements that I always seem to find missing in a DNN blog modules are as follows:
- Categories - I need to be able to categorize my postings. I do not have time to have humpteen dozen different blogs on seperate pages. Categoizing helps with search engine optimization and overall blog navigation/organization.
- Search Engine Friendly URLs - I don't like, nor do most search engines like, parameterized query URLs. dasBlog does a great job with allowing SE friendly URLs, just checkout the URL for this post: http://dnnblog.venexus.com/Why+Are+You+Using+DasBlog+For+A+DotNetNuke+Blog.aspx
- RSS Enclosures - Adding audio/video to a blog is very cool...which reminds me I should start doing some of that with this blog

Anyone know of a good DNN blog module that will do the above???
Until I find the right DNN module, I am going to stick with dasBlog. dasBlog does all of the above items, plus works very well. I would prefer to be able to use a DNN skin than the builtin templates, nor do I have the time for developing a new dasBlog template, but everything else works nicely. I would love to see someone port dasBlog to a DNN module.
On a security note, I ran across this post about a dasBlog security issue. I have upgraded this blog to use .Net 2.0 and have not found any issues with the upgrade so far.
