Yeah, I noticed there are ppl who are only on LJ and not IJ. A Russian Harry Potter fan friended me on LJ, but she doesn't have IJ. Also, on Snarryficfind, I posted my Fatherhood 101 series and got several replies (mainly from ppl with LJs only) that they liked it and had never seen them before.
I suspect if I post regularly and start cross-posting to Snape_Potter sometimes like what some of the drabble writers do, I'd probably get more people noticing that I'm here. I would've been doing this all along if not for having been unable to draw for a few years. I'm only just getting back to drawing after a long time, but there's just so much to do.
