If I had any friends offering invite codes, I would create an account there and try it out. However, did the same with IJ and other LJ clones sites, and never really got into any of them, for one main reason: my flist isn't there, and I'll stay/go wherever the majority of my flist is. Since I'm pretty certain the majority of my flist is gonna stay on LJ and will not switch to DW, I won't switch either.
