Will the forge ever get a livejournal of some sort, for any purpose? It could end up very interesting. Or it could end up tragic in some way. My question is: Has anybody ever though about the possibility?
Starblade,
Several members of the Forge have Livejournals, and post theory and even game development ideas in their individual journals. Additionally, I know that there is an effort to collect various theory blogs from blogspot and other blogsites into a single site. It's not entirely what you're asking, but it is related, and therefore I figured it might be of interest to you.
Perhaps some of the people mentioned will post their journal names (and perhaps they won't.. it's obviously a personal preference). The people involved in the consolidation of blogs will probably post on their progress when they get something they want to show the Forge community at large.
The Forge is a place, not a concept, so I don't think it could ever be LJ'd. You may find these LJ communities fit the bill however:
http://www.livejournal.com/community/rpg_theory/
http://www.livejournal.com/community/indie_rpgs/
Neither of them has seen much activity as yet.
