I've complained about Bloglines's mobile editio and the lack of required, expected, and stated features, so I think am required to mention that Bloglines has updated their mobile featureset and added a few of those missing features. The "keep new" feature is a feature that should have been there months ago, but better late than never.
I've used a couple "real" software RSS readers on my mobile but Bloglines, even with the problems, was better overall. And free (as in lunch). Thanks guys.
I am given hope by the way the new features have been added in a staggered rollout over a couple weeks. Hopefully this means there is more to come.
