Tor does need exit nodes. The graphs on Tor statistics page show that only a quarter of Tor nodes are running as exits. That said, if this is on a residential internet connection you might not want to be an exit node. A few web sites blacklist the IP addresses of Tor exit nodes because they don't want anonymous traffic for whatever reason. Likely you won't encounter such a site in your personal surfing, but you should be aware that publicly announcing yourself as a Tor exit node may constrain you.
Freenode (not the website, but the IRC server) doesn't allow connections from Tor exit nodes, and Wikipedia doesn't allow editing through Tor.
