trivia
hey, I bet you cant beat me in poptrivia. aol's got this like, trivia game going on at http://goldrush.aol.com and its really fun and I bet youll like it and have fun too if you sign up

Maybe not this time...

Let's see, the other one was (paraphrasing here) "OMG! I GOTS TO GET ME SOME GOLD! DO IT YOU'LL GET GOLD!"
Very agressive and shameless plugging.

This one seems to be a bit more innocent, if you will.
It appears here that it's just someone who enjoyed the game (although the "bet you cant beat me" part hurts this argument) and is merely passing it along to others who they think might enjoy it (not the best example, but the M&Ms game, which was clearly just for enjoyment purposes).

Of course I could be very wrong and if I am, let's all sing a Python tune:
Spam spam spam spam. Lovely spam! Wonderful spam! Spam spa-a-a-a-a-am spam spa-a-a-a-a-am spam. Lovely spam! Lovely spam! Lovely spam! Lovely spam! Lovely spam! Spam spam spam spam!

LUCKY! I have to push the pram-a-lot...
