I also happen to love using the Twitter web interface.
What I hate, is the new “Who to Follow” box.
Why do I hate it? First, I don’t need to clutter my Twitter stream by following more people thank you very much. Second, there is no way to collapse or delete the “Who to Follow” feature. I even tried “Xing” every suggested user in the hope that the feature would then give up. Did it? Nope, it just regenerated with a bunch of other names.
But that could just be me. I may be the minority. Maybe you love the new feature. Either way, let me (and Twitter) know how you feel about the new feature by voting below.
