There's nothing that can save you from having bad taste. However, given good taste and not-so-great artistry, Bootstrap is a web developer's best friend, specially if you're looking for contract work or launching your v1 app. And even with bad taste, there are sufficient examples out there to steal, err, get inspiration from.

You're suffering from selection bias as an HN reader visiting other hackers' websites and such who have heard of Bootstrap. The greater extent of the world has not seen Bootstrap, and if they have, isn't it better for them to experience something decent looking?

If you have the chops sure, but a good number of hackers do not have taste, and less have the artistic talent.
