Crossposting (aside from the number of comments issue) does appeal to me, cos I like the stability AO3 offers fandom. The stories would still be there no matter what happened to my presence on LJ. But, yes, laziness has to be overcome first :-D

I do the read only thing too! Though last time I committed formatting craziness that didn't show up in the browser I'd done the dummy run in...well, at least I'm creatively incompetent?

Interesting, do you know why you'd find it difficult?
