As it is, when the visitor hits your site he will see it is not just a general chat site, but a chat site for people in their 20's, and this teen will leave quite quickly. This is bad - you want visitors to stay a while, chat, see a bunch of ads, bookmark your page and come back, etc. We are trading traffic that is almost worthless to us but very valuable to the person we are sending it to - and both are benefiting. In the event that someone was interested in both Teen and 20's chat, he would visit both sites, and the one that was best designed he would bookmark and return to. It's pretty much a win-win.
Many people automatically think of a links page when they think of trading links.
This is a great way to exchange traffic for identical interest sites, or unrelated sites. We encourage this. Try to think past conventional trades however - you could trade banners on your main page instead of using a link exchange programs and not lose those extra impressions to the person running the program. You could place small links to each other on the bottom of your main page, or on the side, allowing visitors who don't make it to you links page to be exchanged. If you run a different type of site, be sure to check out discussion board - we have a special message board for webmasters that want to trade links and traffic.
