Ask HN: What do you consider too long for a domain address?

HNers,

I've been looking for a good domain name for my recent project. After going through all my top ideas (noticing that they are taken and put to no use), I'm starting to play around with words to find something good (after all a good name is important, right?!).

However, it appears that all of the names that i am finding are long, or at least I think that they are long. So I have a few questions as I am sure a lot of you have had to deal with something similar.

1)What's considered too long of a domain name?

2)When it comes to domain name length and quality(witty, catchy, meaningful), which do you sacrifice for the other?

3)What do you look for in a name, anyways? Wit? Catchiness? Meaning?

Thanks!
