So how have you named your startup or web app?
Usually I have a fair idea of the kinds of words I want around a project, the thesaurus gives one or two alternatives that I had not thought of (English 2nd language here), then I use a little program I wrote that tries to pull together two or more words based on a dictionary extracted from project gutenberg.
The resulting words are looked at one-by-one, promising ones go in to the 'register multiple' field at moniker, when I have enough I submit, check to see if any of my favorites came back as free.
It's time consuming, sometimes as much as a day for a good domain, but it almost always works.
Remember to always do some research on your chosen name before you actually name the product.
As long as you're the least bit creative, after a while (days, weeks,...) your brain will come up with something.
Try deforming an existing word à la Google, try combining two words into one (techcrunch), try using numbers or you can even try and invent a new word.
Squatters can't buy up everything, there are still options.
