"what is the problem your solving?"
"who is this for? what's the market?"
"where is the unique or different element?"
"how is this idea going to make money?"
If you even feel yourself even somewhat considering attending a Startup Weekend, I'd say skip the usual weekend routine of watching Chopped re-runs or getting mastering the every country in Europe Sporcle test and try it out. You can't really use the excuse about having trouble finding one because these things are literally everywhere. The weekend gives those whose attend a great opportunity to see what happens when programmers, designers, and businesspeople come together for a weekend and build out some really great ideas.
