Is it better to: -create a name using a combination of existing words? (e.g. MySpace, RadioShack, etc.) -create a name that doesn't really mean anything to a majority of users (but possibly memorable)? (e.g. Twitter, Tumblr, etc.) -create a name from existing word(s) but change the spelling for funkiness? (e.g. Digg, Reddit, etc.) -create a name derived from another language?
