I don't exactly look for specifics often, but if I'm in a mood for a general "type" or genre, I like to see what's available when the mood hits (.. so like several times a week).
I'm not looking for them. I don't use search engines. I have browser tabs open all the time on the Latest Updates sections of a number of sites. I look through them twice, in the morning and in the evening. If I'm interested in something, then I download it.
More than what should be considered healthy, few times a day I'll poke in and see what new in the feeds. Wont frequently obtain something new but once in a while a gem pops up adding to ever growing pile of titles im waiting for a few updates do drop (or watch as they frequently get abandoned)
