How to choose a name for a web app?
epi0Bauqu: First, some meta-advice: start the process early and let it go for a long time.  Keep thinking about it and talking to people about it.  I find that good name ideas come over time and come in spurts.There have been some good name posts on news.yc, so search for those.  What I strive for:--As short as possible.
--Memorable (often through rhyming, alliteration, repetition, etc.)
--Something people can spell.
--Something related in some way to the app (this is just my preference).
--Easy to pronounce (e.g. people know where the accent goes).
--Good connotations (or at least not bad).There is also some psychology involved in certain sounds, but I forget the specifics of at the moment--search for it.Finally, I find instantdomainsearch.com, a rhyming dictionary, webster, and a thesaurus useful tools in the process.
