I'm Ithildin on IJ (the one point it has in its favour!) and here I am. I'm not leaving LJ though. I have a permanent account, a huge portion of my friends are here, and I like the way LJ functions. If something earth shattering were to happen that I had to leave LJ, I'd probably just spin off another blog on my domain and then people could track me via RSS on the their f'lists. IJ and GJ are just too annoying interface wise for me to see using them at the same volume I use LJ.
I'll be using IJ has a place to hang out whenever LJ has an outage, and while I'm not going to crosspost everything here there, I will start crossposting fic to keep the account active and as a sort of secondary journal type archive.
So not going anywhere. Sorry, but it looks like you're stuck with me here for the foreseeable future.
