I'd dipped my toe in the Google Reader stream for rss feeds some time ago, and am not convinced that Bloglines is any improvement on it.
For my taste, Bloglines is graphically confusing, with each blog's own icon and font displayed; entries in Google Reader look more consistent, which makes it easier to scan new subscriptions. Google's 'Recommendations' feature also is working better at the moment, but I may revisit that in a day or two, when Bloglines has had a chance to compile some recommendations for me. One from Google Reader that's currently relevant for me is
Library Web Chic.
I did like the discovery tools, especially Technorati with its ability to filter for videos or other categories.
Topix was a bit overwhelming with its quantity of news, but I did see that one of the most-talked-about threads was from Okfuskee, Oklahoma which of course I had to investigate: a shameful story about an Oklahoma Highway Patrolman's assault on an ambulance driver.
Syndica8 didn't do much for me; it appeared to have fewer relevant links for my searches. Maybe it's just a measure of how this exercise develops my expectations of instant gratification; if I can't understand a tool or get results on it without having to consult the Help screen, I tend to discard it in favour of the easier ones.
I could not get the Share feature of Bloglines to work, not even with Tony's and Adriana's useful instructions, so alas I am unable to share with all of you my vast range of interests. I do now seem to have renamed my account BlogsFromBarbara so if you're really keen you can probably look it up.
