In looking through my server logs, I see a lot of daily requests for the RSS files - from a very wide variety of newsreaders. However, there have been no requests at all (at least not yet) for the atom feeds. There are atom feeds for all the blogs hosted here. Now admittedly, other than this blog, I don't really advertise the atom feeds. On the other hand, I haven't had any requests either. At least from my viewpoint, atom - as a syndication format - has dribbled off into irrelevance. RSS, for all its warts, is the format that is actually in use - and that's unlikely to change.
