I tend to do all of them, depending on my mood. Sometimes, I preview it and re-read it before submitting, sometimes I edit after submitting, sometimes I type, read it for once more and submit. Mood is the main stem which varies for me. But for most of the times, I do the first option (even now, I'm doing it lol) so my vote goes for the first.
I normally edit as I go. It's a somewhat tedious process. Y'know... type a sentence... reread it... edit it. I don't always catch everything though, so the EDIT option has always proved quite useful to me Sometimes, I just type and I really don't give a fuck about whether or not I made a mistake It all depends on my mood I suppose.
I do a lot of editing afterwards. LIKE I AM EDITING RIGHT NOW. What I mean by afterwards is after I clicked submit, then I see all these mistakes and I go in and try to correct it. It is extremely hard to see the whole post on the iPhone and easy to make a mistake when posting from the phone. If I am on the computer and submitting it then I might go over once and hit submit, after I took out most of what I was going to say because I have a tendency to go on
I almost always read things over a few times just to check the flow of whatever it is I'm writing. Of course, sometimes I just don't care and post whatever and worry about the consequences later. Usually after a few drinks.
(I've mentioned drinking a lot recently, which is funny as I rarely actually drink. Of course, every time I do I somehow end up here. :blushed: )
