Because everyone comes here first for Bitcoin and then starts reading about other coins.
Secondly this forum is clearly the center of the Bitcoin AND Alt. Crypto communities.
Unless an announcement about a new coin / currency isn't posted here it doesn't exist.
(Even ripple had to post here and give hugh giveaways to gain some traction - ok, it backfired but still).

This messy sub forum for all cryptos is simply overwhelming and non informative anymore.
