Just giving a shout out to Ander Wood aka woodwward on youtube.
He puts together some great instructional D&D videos on the sight, helping players and gms to keep thier tired, stale old role play styles fresh.
He helps re-imagine what monsters like trolls and ghasts really are and creative ways to use them in your table top game.
Often gives view points on some of the various rpg products out there as well as some videos on collectable "toys".
Check him out and give him a view if your into that sorta thing.
