content is still limited enough that manually looking through most things doesn't suck too much.
but when this game launches, i bet there's going to be lots more newbies -- would be easier to navigate the flood of discussions, groups, and encyclopedia entries with a search function. and, it'd encourage people to interact more with other players!
for groups, categories/tags (e.g. location, game play, guild, etc) would help in finding the appropriate groups to join.
