Seriously. This BNET article has a bunch of examples of tweets sent in response:

Not a good idea. Could be Stewpyd

Sci-fi channel is rebranding itself as #SyFy? so obviously ludicrous it must have been formed by consensus.

Actually, I’m going to start calling Sci Fi Channel “siffy”. As in “syphilis”. As in “neurosyphilis”

Just conducted a quick experiment: It took 5 pages of search results to find a positive response to #SciFi -> #SyFy name change.

Will they back down? Pepsi reversed track on its Tropicana generification after tons of negative response. It’s hard to find any positive comments on Sci Fi’s blog post about the rebranding.

Well done, Sci Fi. Friends and I joke that perfectly good names need more Y’s in them, and you’ve taken that joke and run with it!
