I find that many already know about Pinterest, I have a pinterest account as well. But if you are remodeling or just looking for ideas on home improvements this is where you go. I always recommend my clients search there for ideas if they are not sure. Or if I am not clear on what their vision is, I ask them to check it out and find something similar to what they have in mind. I work so much better with a clear idea of what a home owner wants the finish to look like. So if you are tossing around thoughts of a remodel, builtins, large or small - Look here. There are also plenty of pros connected throughout the U.S.
A great place to start if you need ideas.
