These names are cool, but I'm afraid they suggest a connection with stars or astronomy or science which isn't what I want to do. The name either needs to be completely specific about what I do (matthewebdesign.com) for example, or completely abstract (pocketsoup.com)
To give you an idea of the names that work well, here are some used by big names in the industry:
snook.ca (the persons surname, short, catchy)
zeldman.com (the persons surname, short, catchy)
stopdesign.com (a play on words -- a web design agency)
mezzoblue.com
meyerweb.com
molly.com
veen.com
37signals.com
etc... you get the idea -- these are short and catchy. Using your own name is obvious and where the name is made up, it's almost always a fairly mysterious combination that doesn't really mean anything. Using possibly real phrases like molecularimages suggest I produced images of molecules.
