Somebody's been there and done that in NYC! Remember Blink 102.7? If you blinked, you missed it!
I think Blink was a great idea, done badly, and was hurt by the fact that it replaced WNEW-FM.
Had it replaced WFME, it might have had a better chance.
If Randy Michaels does a Blink-like format, replacing a format that doesn't engender a lot of passion, using well known female hosts, like the letters I mentioned, he could do well.
