I just saw that if you post by web there is a „tags“-field with auto-completion.
Is that new? I usually post by email and haven’t seen this before. When you edit a post it’s not there, although i think it would be nice to have it here. (correction it actually IS there, when you click „more post editing options“ sorry for that.)
Even more important for me i’d love to have a tags-field with auto-completion in the bookmarklet … as well as some other things mentioned before (ability to choose where to autopost etc) :)
Anyway, glad i found this.
edit: oh my, i totally missed this post, so, … thank you Posterous! :)
