I believe I’ve been using beta.bloglines.com for long enough to comment further.
– I’m still seeing some sync problems between the the number of new posts shown on the left column and the actual number. This forces me to explicitly click on “Mark All As Read”.
– I really miss the smooth scrolling from post to post which is in the classic bloglines.
– Given the travel I do and the many different internet connections I use (home, office, customer or public wifi) I feel this new AJAXy version is just relying too much on the network to be there at all times (but isn’t every AJAX app?). I actually move back to classic bloglines to download entire pages of updated feeds (it marks them as read) for an off-line read. This begs the question: off-line anyone (even using gears)?
– One more thing I miss from “Classic” Bloglines is the smooth scrolling from post to post.
