Well, I'm going to delurk to support Gleemax.
First: What happened to Dreamblade! I thought the trifecta was going to be Magic, D&D, an Dreamblade... Hmmm....
Second: Gleemax is being described as NOT a news site, NOR a simple message board about a specific subsegment of gaming. I don't see how Gleemax will be a competitor to Enworld any more than Hordelings.com, or BGG.com competes with Enworld. Many people have accounts on multiple messageboards, and everyone gets along just fine!
Seems to me that WotC is being pretty brave. They clearly don't have a sound economic model, but they "know" that Hobby stores are central to the "next generation" of tabletop games (That is board, card, and pen and paper games). They know that this effort will likely help their competitors as well, but they see that a rising tide saves all boats (or what ever the saying is...).
I don't have a my space page... but I'm likely to build a Gleemax page. The hardest part of staying in gaming once i left college was finding a new group to play with. I graduated in 1994, and moved to Portsmouth NH, and knew NO ONE. I took me 5 years to find a new group to play with. In college I used to play board games ALL the time. Particularly the ones that take a while, like Diplomacy, Advaced Civilization etc. I still haven't found a group of people near me to play those games.
The idea of having your own personal page that calls out the games you play, so that others in the area and seek you out is great. Likewise, finding out that store XYZ which is only 20 minutes away is gong to try a D&D Miniatures tournament is great!
Sure, the Gleemax name is a bit odd, but not THAT odd. It's a name, and it will be taken in and converted in our own minds... I still think Revolution would have been a better name, but as the Wii was a strong console, it doesn't matter!
Don't be misled, why Gleemax won't have the DI content (i.e. no Dragon and Dungeon Content), they DO what D&D players involved... I've never played Magic outside of my home in 1995, and the DCI doesn't know me for magic, only for DDM. But I received a brain. As did many like me. It looks like they want ALL kinds of gamers so that they get good cross pollination...
