question about hyphenated web domains?

[Jake]

Two hyphens doesn't seem terminally bad, historically hyphens were considered acceptable word separators and were thought to not harm ranking beyond adding to the character length, realistically like a .com is perceived to have more value than a .biz, it's a pain to type hyphens mking them less desirable for type in domasins found in print.
A Google insider reportedly said that multi hyphen names were counted to measure the effectiveness of spam site filters.

The hypens may be a disadvantage that established site age may overcome, I agree a 301 redirect will pass link juice to a new site, though I would expect a dip for a couple months in any transition.
