A lot of my friends use Delicious scripts to get their bookmarks onto LJ, and that requires some seriously annoying hacking--getting it onto DW would be great, especially if it can be done without hacking and by converting whatever encoding they're outputting (we think it's western european) into UTF so posts are editable.

It'd be good if, for the simple purpose of allowing a client to post, we supported as many APIs as possible, as sometimes people are restricted on what they can install or use.

But full on editing, exporting and similar can be restricted to getting one decent API that works I suspect, as long as it looks fairly future proof.
