Cool stuff. How are you grabbing the words? Did you download a dictionary?

When I submitted my URL I got "constituent", which seems unnecessarily long. You should consider having a list of short adjectives and a list of short words, preferably with both being one syllable. Then you grab one from each and you get short URLs that are still easy to remember like "redbear" or "fastbulb". The best part about this idea is that it reminds me of the monster names in Diablo 2.

I'm using a modified copy of the standard linux dictionary word list. I took out some variants of words that I thought would be confusing or hard to spell. I thought about using 'word tuples' as you describe, but I think that would be more confusing and less useful overall. There should be enough single words to make this work unless it gets insanely popular (knock on wood).

I find a combination of a few short and common word easier to memorize than one uncommon one. It's even easier when it makes somewhat sense, like an adjective and a noun.

I got 'constituent' when I tried it too. That begs the question, what happens when you accidentally try to go to an expired url that has been reassigned? Like say you hit a url 1 minute after it's expired, and with bad luck it's been randomly reassigned to an NSFW link?

Maybe a landing page before you actually end up at the link?

Constituent is much better than redbare. There's nothing wrong with being long. Homophones on the other hand defeat the purpose of the service.

Constituent is something most non-english-speaking people will have a really hard time spelling.

I feel like this is clearly targeted at English speakers. Implementing alternative languages would be trivial anyway.
