Of course if youre doing something legally grey like youtube or file sharing, then perhaps you should incorporate. But without any assets in the company, the corporate liability will most likely be pierced in court.
As for a LLC. Its nice but you should really do a ccorp if youre serious about business, and changing from a LLC to a ccorp is a pain in the butt. Or so I hear.
To go further, I challenge you to show me a single case of a company being sued that wasnt doing something legally grey and not making any money.
