Yepp, people would probably use it, if it's easy to remember (can't say that .cjb.net is easy to, but think new ones must be more memorable)
But be aware that when your service grows, some problems arise. SPAM. I hate those %&/%/% users that uses a service that is provided for free, clearly states that SPAM is not alloved, and that has costed me alot of work, just to be able to spam others with their nice new cool domain.
Right now I have to go out hunting for a new server, as our current ISP got upset with the complaints he got about my users. And I that was prepared to release a new better version.
Anyone who has any ideas how to stop people from spamming??
