So far, LiveJournal isn't one of them. Websites that aren't optimized for wireless devices are kinda sluggish over a 14.4 connection. Does LJ support RDF or RSS output? Has someone written an AvantGo-friendly style? If the answer to either of these is "yes", is it documented anywhere?
Tangential question, in case anyone here knows the answer: What's the best way to get a small simple web page, suitable for a sidebar or an AvantGo channel, out of an RDF or RSS feed? I could hack one together, of course, but this seems like such a common thing to want that someone must have done it already, and probably someone with better design sense than me. :-)
