Need Ideas for a web-site


Me and a buddy of mine are having thoughts to put in our creative minds into making a web-site/community, basically anything that will bring some sort of income, obviously ads can be put on the site, but i am talking about a site that would offer some kind of help/material that can be sold. do you get my vibe? share some ideas, what would be good these days? what do people want and what do they need? list some ideas please. be as broad as possible!
