I did look it over the other day, and it looked like no ads on the journals themselves, which really is the main reason I don't do a plus account. I don't mind them so much on RP journals that don't get many entries, but they just... bug me. I basically pay for Dirk's just because I want the lots of icons space. On the other hand there's no point moving him over when the RP is here.
What I really wish is that all these platforms were interchangeable, since the scripting is basically the same. That you could post to an LJ come with your IJ and vice-versa. Not gonna happen, but it would be nice. Might make them more competitive and drive them to be nicer to their customers, really...
