If your speaking about Facebook's API then that the decision on whether to use it is highly dependent on the purpose of your site. Personally, I would think very carefully before branding your site as a Facebook addon. You might be referring to Thrift. In that case, it's only useful if you want to do cross-language services. I don't think an early-stage startup needs this sort of architecture but I guess designing for scale never hurts.
