Bodog is a medium-sized site. There are a lot of other smaller ones, but the really big ones (Stars, FT, Ipoker, Party) all routinely have at least 5 times as many players as Bodog.
Whether this is a good or bad thing depends on your interest. If you are primarily a Ring Game or STT player, more traffic means more choice of tables, which is good.
However, if you are an MTT player, the really big sites arguably have too much traffic. Their tournaments tend to have larger fields and take noticeably longer to play, which may be inconvenient and may actually mean that one`s options are fewer.
