BlogRoots, the weblog about weblogs, is adding product descriptions and reviews. I took a first stab at describing Radio Userland, which remains a challenge. There's a perception that it is only useful to programmers because the scripting and database features are sophisticated, but I think it's also a good choice for beginners who want to start a weblog quickly without messing around with HTML, FTP, CGI, or the like.
Except for the bugs
What significant bugs? I'm using Radio Userland every day to publish a weblog, read feeds, and aggregate other XML, and I haven't encountered a bug of any significance in months. There are undoubtedly bugs -- some people are having a weird first day of the month problem, as mentioned on the Radio Userland discussion forum -- but in my experience the software is reasonably reliable.
