1. Blogger increasingly sucks. It choked when I tried to give a post the title "I <3 Pinterest." I'm assuming the caret was verboten. Seriously? No "<3"? And have you looked at the HTML after you create a post in compose mode? MESSY.
Relatedly, are you on Pinterest? It's basically a visual bookmarking site, a place where you can share cool things that you find around the interwebs. I totally dig it. If you'd like an invitation, let me know!
2. The mobile experience is prohibitively abysmal. It's almost impossible to use without making me curse at something, and there's no way to back-date a post.
3. I'm still really ticked off at Google over them ditching Reader's social features. Here's a more coherent rant about why than I can provide right now.
Can anyone think of a reason not to switch?
