Something I learned from my own website (the MST3K one) is that most people that say they want to do or are going to do something, don't. The key is to do something, then tell people about it when it's done.
I hate websites that say "under construction", because they never go to the "constructed" phase and just die on the vine. If I add a new feature to my site, I just do it and announce that it's done. Saying I'm thinking about putting up a new section doesn't help anyone and I'll just be adding to the lame on the Internet.
^^^ = announcing isn't doing.
