Ooh, this is kind of a toughie for me. Though... I do not constantly post on my blog and usually only post when I think something is worth mentioning -- which is an event that is usually either A) one that deserves a gold plated frame as the special feature in the Gallery of Grandiose Moritification (the most likely circumstance, and yes, I do love to stare at my humiliation and burst out with laughter); or B) one that simply requires the juicy, detailed descriptions of my fantastic love life (which is hardly likely as I do not own a love life, much less have a fantastic one *chortle*).
So blog postings aside... *cough* I have a hard time choosing between Xanga and LiveJournal. With Xanga, I enjoy coding the design of the website. ^__^ And... perhaps LiveJournal (LJ) does let you do this too (I really need to explore that bit a little more -- and hey! If it does, another pro for LJ. ^__^). But for LJ, I mainly love its communities. ^__^
