I am not one of those who might care too much about other people's blogging or blog editor problems (my Firefox spelling editor didn't know "blog" or "blogging" right now!), because I have not yet started a blog myself. But of course one day I just might, so I am curious how to maybe do it via Firefox. Did you try ScribeFire (or maybe you don't use Firefox or Chrome?) which some of the posts spoke so highly about?
Well, like I said, I wasn't really looking for a blog editor.
As far as Scribefire goes, I haven't used it long enough to encounter the formatting problems but for the most part I find blog editors to be slow compared to gmail and their cramped spaces don't allow for the length of blog posts I write compared to full screen/pop-up gmail textbox.
They're also for the most part "worrisome" to save drafts into and they still have options that get in the way compared to an e-mail box. I compare it to using Word over notepad.
In the end it's different purposes though. Blog editors are for backups while gmail is for me, ease of editing/typing over other editors with minimum fluff except what gmail offers.
