No, I have a permanent account here on LJ. But with DW's crossposting feature, I may switch to posting there and cross-posting to here. Especially if rumors about being able to read accounts on other blogging services on DW prove to be true. I've been frustrated with having to log into multiple journals (LJ, IJ, GJ (before it folded), blogger) just to keep up with everyone and then having to deal with seeing duplicate posts made by friends/communities that cross-post. If DW solves that, I'm all for it. Especially since they appear to be committed to keeping their code open source and actually making improvements to the code.
But I won't lose you and you won't lose me.
