I found a domain search engine (that doesn't exist anymore) that let me filter domains. I wanted a 6 letter domain or shorter that was meaningful. There weren't that many options so I only had a handful to choose from. I got dixxo.com and dixxxo.com as well for $9/each. I also have hublify.com and dropclock.com. I didn't really know what product I was building but I had those domains. It wasn't until last month were I pulled efreeme.com out and started using it... The point is get a good domain, and you'll never know when it might come up that you could use it.
