Something of a different link, this takes you to (a very good) message board.

Baseball Fever always have some great projects going on that should pique the interest of most baseball fans, but this is one of my favorites that has been going on for almost a year now.

They essentially started the Hall of Fame from scratch and, beginning in 1900, allowed the posters to act as Hall of Fame voters and started going year-by-year to see what their own Hall of Fame would look like. Each year lasts a week, and it's a very interesting -- if vastly less serious -- look at being a voter. The discussion that comes up is often an informative and interesting look at history, as are the different attitudes the people bring in towards what makes a Hall of Famer and how they determine that. And it's also entertaining for me to come up with my own ballot every week.

In any case, if you're a baseball historian, like polls, research, and like arguing about and discussing the Hall of Fame, it's probably your thing. Right now they're in 1944, with that vote closing after today (I'll change this link when the new week comes up). In that thread you can find the entire HoF through the first 43 years of voting.

And here you can find the Progressive HoF archives.
