This is interesting. I'm blind, and while I can think of ideas for products/side projects, designing a nice-looking website is such a huge momentum-killer. I mean, I know that I could just focus on features, keep the site design simple, and build a good design later. Then I visit , and half the comments are about how some UI element or other breaks on some combination of browser or other, and the last thing I want is…
While Bootstrap isn't a silver bullet in general, it's surely great if you don't want to write CSS, or only where necessary. And you can always build on top of that.
And needless to say, tastes vary wildly: I once started a side project with someone who was virtually my taste counterpart - he liked everything I found ugly and vice versa. So maybe you should get a second opinion on your designs... :P
