As other people have said you should be able to boost your income with affiliate offers. Pool, enom and snapnames all have programs. Where domains are registered with network solutions you may want to default to snapnames. For all other domains try some A/B testing and go with whatever pays the most.
It has been suggested that you add in link counts. My understanding is that the search engines, at least google, tries to discount links received prior to a change in ownership so I'm not sure this would be useful from a SEO standpoint. If you're interested in natural clickthroughs then it may also make sense to add in alexa/compete traffic stats.
The regexp gives a lot of power but many people have problems constructing them. I don't suppose there is a WYSIWYG editor for regexp is there? I would certainly take that form out to a page of its own and add a cheatsheet. I really don't think linking out to wikipedia is the right solution. Provide your users exactly what they need and no more.
You need some way of encouraging users to return. Subscription to a regexp search has been suggested. Weekly featured domain might also work. Email and rss would be good. Might also be useful to have a tell a friend function though the audience is probably wrong for this to work.
It would be good to be able to construct more complex sorts. Deleted and part of speech for example.
