Yep. As mlk-man points out, I am a newbie, looking to learn. Ever grateful that people here are willing to share what they know and answer stupid questions. And to the folks, such as yourself, apparently, and mlk_man, who do the grunt work.
Whether RevShark or ST do well or poorly isn't the issue. It just isn't cricket to blab their moves, even if they suck. There's a lot more to running an internet business than blurbs on a message board.
TSPTalk'ers (or ST or RS) haven't publically traded TSP funds long enough (2004, max?) to evaluate. Who's leading the pack YTD or FY2005 is interesting, but at the timescale of federal careers and TSP participation, it's peanuts.
RevShark, on the other hand, is demonstrably the real deal, tho perhaps others merely posting here have equally distinguished, long-term records. Learn from those who do.
As far as business models go, I think the conflict is more apparent than real. TSPTalk is a newspaper, a one-stop TSP shop. Dick, and Harry believe in their product and want to sell advice. Tracking their results along with everyone else's in the town square is both advertising and validation. If RevShark has an exclusive w TSPTalk, presumably that factors into the RevShark newsletter price, but in the long run that exclusivity undermines TSPTalk' credibility.
