I think the point that an uncustomized Bootstrap looking just as tacky as a plain html site is only true for people who hang around on HN or similar sites and so see many different sites using Bootstrap. For your average Joe on the internet, a Bootstrap-ped site will look much more professional and less tacky than a plain html site. So depending on your target audience, there might not be much motivation to spend any time customizing your site.
Bingo, give this man (or woman, or whatever) a cookie. Not everybody is like us, scouring the internet all day long for new startups and clicking every interesting link that shows up on HN. The average Joe off the street has probably seen 2 bootstrap based sites in his life, and has no idea what bootstrap is, and couldn't care less that a site he's using looks nearly identical to 3000 other sites that he'll most likely never visit.
This whole "bootstrap backlash" is just a storm in a teacup and a waste of bandwidth.
+1 (and a cookie). Average Joe is used to seeing sites like http://www.universityinnfresno.com/ or http://www.sunnyvalemetro.org/ and so, a clean site based on Bootstrap is a ton better than most of what he comes across. The # of Bootstrap-based sites is a tiny, tiny sliver of all sites out there and no one other than your dedicated HN-reader is going to come across a 2nd Bootstrap site the same day.
Heck, I hang around on HN a lot and still think that the default Bootstrap theme looks great. Sure, a little variety wouldn't hurt and I'd probably change some stuff (like some of the colors) before deploying a real project with it but it looks and works great and it's better than anything I could make as a programmer.
This. 100 times this. For the people who actually matter (for non design/web related projects).... the customers, they do not even notice. If you aren't going after designers, or web devs themselves, bootstrap looks very professional....and I for one, am not here to stroke designers egos, but to make money.
