What exactly is BBQ coin?
It is similar to Tenebrix, that is, it is a coin that CPU miners were left undisturbed to mine for many many months before the GPU people came back and drove the difficulty back up again.
So like Tenebrix, and Bitcoin, it actually got to have a long long time for small miners, ordinary people who don't even have a GPU, to get some coins. It is thus a "fun" and "grass roots" coin, a coin of the ordinary people, or at least it used to be before the GPU people came back to it. But the CPU people had lots of time to pick up coin, so unlike with things like Feathercoin where they never even had a chance, this time around they actualy have some coin when finally the thing gets onto exchanges.
It looks a little right now as if GPUs might be coming back to Tenebrix, too, so very soon the era of CPU mining for that too might finally end, maybe. (Lets hope the GPUs leave it alone a few more months though, as a lot of newbies without GPUs are still arriving, it is nice for there to still be, all this time, a coin they can effectively mine.)
