What do you mean, this site has become boring? Are you just impossible to please, or is the activity here not to your liking? Either way, as it has been said previously, do something to fix it instead of complaining. We post what we're interested in, and there's a shiny, brand new, "Post New Topic" message box at the bottom the MB for you to talk about what interests you.

For example, I love free books, so I post any time I find free books. (shameless plug: look for my posts on the Sci-Fi/Fantasy MB for free downloads!) Other than that, I'm largely silent.

You're right, there's not a lot of activity on most of the boards. TV&Movies, Games, RPG, sometimes days can go before anything new is posted. But if Sci-Fi/Fantasy is too dead for you, go over to the WoT boards. Or even the CMB, although I strongly recommend you get a full set of vaccinations, including smallpox, rabies, and H1N1, before you actually post there.

In closing, this site is what you make it. If it bores you, make it into something interesting. I'm sure that someone else shares an interest with you, maybe even multiple someones. But you have to make the effort. I know you can do it, I believe in you!
