I have to say, that was one thing comment fics were good for (thinking back to the really early days for me...all of 2009ish). It was okay to just be terrible, because on the whole everyone was nice about it, and you don't have to face those first few atrocities ever again. Though I do have few old shames still lurking about on fanfiction.net, they're still not as bad as the first one or two I remember doing. Oh god, they were bad.
