Newsgator
I'm trying out the posting features of Newsgator using the B2 plug-in. (So Andy I might be able to improve upon my spelling ...)
[EDIT] Okay this thing actually sucks as it's shoving loads of HTML (like font and paragraph tags) into my posts.
And when pressing Ctrl S the damn thing posted the entry instead of saving it! Then it thought the item was not posted so after making changes if offered to post but it did nothing :P Think w.bloggar will be fine for me.
