I installed Sharpreader just yesterday. I've used it off and on over the last two years, but it had been awhile since I last used it. I always thought it the best RSS reader and thought I'd check out the new features (and find out if it still works w/ my blogging software). Well, surely enough, it did work w/ my blogs. So, I loaded up a few dozen feeds and at least 10% failed, for one reason or another. In some cases, it was a bug in Sharpreader, but more often than not, it was buggy RSS. I'm amazed how much RSS still doesn't validate. In fact, several bloggers who write frequently on the topic of RSS and contribute to Atom, had invalid RSS feeds. What a state we are in. I don't expect your RSS feed to validate 100% of the time, even mine doesn't do such, but if your RSS feed validates 0% of the time, then few are actually reading your blog w/ an RSS reader.
Let me get back to Sharpreader. I haven't seen much improvement of late, but I note it now supports Atom. It's still the best RSS reader that I've used.
Update: ScriptingNews doesn't work very well in Sharpreader. The feed looks ok, but I think Sharpreader is failing to use the <guid> element and is causing some of Dave's post to appear in duplicate.
Just a compile an OPML list of the top few dozen contributors to Atom, import it into your RSS reader and you gotta da names.
