You don't have to join "self-congratulatory ecstasy", but you also don't have to be a condescending dick.

Instead of making vague and shallow insults, you should try to politely explain what's wrong with OP's website.

In your 1-sentence insult, your main grudge seems to be that the website was made by a female. Your point might have been that women's work should receive equal praise (and criticism) as men's. But instead of discussing that (possibly valid) point, your sexist remark only feeds the fire (and makes you look like a dim-witted fool).

In a latter comment, your metaphor compares making social networks to gold rush. Again, possible valid point, burried behind a condescending sarcasm.

We shouldn't read between the lines to understand your point of view -- either make it POLITE and CLEAR or GTFO.

What's with the cynicism? Jennifer went from nothing to a web application using modern technologies. That's cool. I don't think she's aiming to be the end all of social networks for food.
