@ TE,
Link is now up, at the bottom of the homepage; it reads "Join the discussion."

Good thinking about what I'm thinking, although it was actually more oversight than it was part of the master plan
The homepage hasn't been touched in months, since before the boards premiered. That's fixed now.
The homepage will change anyway with everything else when the new site design premieres. The plan right now is to have a newspaper-style homepage like CNN or the New York Times, and there'll most likely be a link to the boards in the top navigation bar for easy access. The idea is to get people focused on reading content, rather than buying programs. Subscriptions will happen naturally if people get value out of the content and want to keep reading.
