Wow. Got a lot of minus points for stating that I'm not a fan. Guess I should've elaborated.
Perhaps I should've spoken about how I think half an hour is cutting it a bit tight.
Perhaps I should've mentioned that the background-image idea isn't too smart, as it leaves too much room for erring with non-fitting imagery. That's part of what designers do: they know what fits together - you shouldn't expect programmers to be able to do that. And if you're really set on educating programmers, maybe talk about the background-image's colors, composition or contrast. Or maybe suggest a totally blurred image or something gimmicky that will make it an "instant hit".
Perhaps I should've mentioned that making bootstrap not look like bootstrap in half an hour, inevitably means that you're going to end up with a lesser product. Bootstrap has been designed from the bottom up. You either use that and it's default features, or end up with a hybrid that looks like you "tried to make a half-decent site in half an hour".
But thanks for the rage points there. I wonder if I could make up some points by posting "I'm a fan" elsewhere.
The reason you got downvoted is because these thoughts should have been the ones you shared. Hacker News punishes tiny comments that add nothing to the discussion. So, you're not a fan. Tell us why.
