I would be shocked if GoDaddy didn't underprice the competition in their initial public offering. The question is whether or not the new product line will be a flavor of their relatively oversold / underpowered hosting the community has talked clients out of using the past ~5 years. If GoDaddy can impress the informed (read: not their typical customer IMO) then they may find traction with the WordPress community.

If it's a substandard offering, I predict the community will continue to badmouth them and poke fun at every misstep, AKA business as usual.
