Personally, I believe that the Semantic Web will become mainstream in the next few years (I actually have a bet on this with some college friends). I know that this is a strong statement, but I am confident that it will happen. Mainstream is defined in Wikipedia as “the common current of thought of the majority”. Furthermore it states that something is mainstream if it “is available to the general public” and it “has ties to corporate or commercial entities”. However, how do you evaluate if something is on the verge of becoming mainstream? I propose the following metric:  inclusion at the South by South West (SXSW) Conference!
