> I’m sick of seeing the same damn buttons. I’m sick of seeing that same damn toolbar up top. It’s driving me crazy.
Take this advice with a grain of salt. As much as I agree with this statement, the fact is, if your audience isn't a group of people familiar with bootstrap, then this probably won't be a problem.
Are you sure you meant Web Developers? It sounds like you meant Web Designers.
I wouldn't use Bootstrap for any client-facing website, but other agencies I know have tried it and those that work on the lower-end of the client scale have had trouble with clients not wanting to pay when the look of certain elements looks almost exactly like those on other sites they've been to.
Bootstrap is a decent tool, but it has been abused by non-developers and non-designers that cannot develop or design their own pages. It's hardly surprising, and it's a testament to how good Bootstrap can be. However, I hope that Twitter eventually scales back some of Bootstrap to allow people that use it for its intended use to get more out of it.
Most of BS's javascript features need to be loaded separately and if you use LESS, you can scale back a huge chunk of the CSS if you don't plan to use certain CSS features.
Additionally, if you spend any time looking at the uploads to Dribbble, a lot of those layouts look similar to each other regardless of pre-existing templates simply because they needed to get something up fast or they just liked another person's concept so much that they took it and modified it just enough.
That being said, it'd take a few seconds to change that black bar to a brand color to make it look passably different.
However, the vast majority of users don't give a half a cent about what UI framework the site is using, let alone know what a front-end toolkit is. All they notice is that it is easy for them to interact with the app, probably much easier than if the developer had coded it. In fact, the site is probably built sooner anyway since the developer didn't have to spend the time to create a UI by themselves.
