Some RSS converters and readers…
Judging from my site logs, apparently EarthLink the ISP offers their own RSS reader. Here’s the user agent:
Agent: myEarthlinkReader/1.0 (http://reader.earthlink.net/; 1 subscribers)
Another user agent I’ve seen in my logs is BASS/2.2. From what I could gather from the homepage, BASS/2.2
BASS is an audio library for use in Windows and Mac OSX software. If it’s merely an audio library, I don’t know why it appeared as a separate user agent though - although the visitor was listening to a podcast mp3 on cleverhack.
