I'm not nearly as active on Pinterest as I was but I still pin and poke around pretty often :) Most of my boards have names that are relevant to me, if they sound cutesie it's because I think of them as being cutesie lol
As far as followers go, for my boards, it's been all about the content. My Hearth and Home board seems to have the most followers. I live in a log cabin so that board is mostly log home and decor. I also have a board full of sunsets that has a lot of followers. Strangely enough boards I pulled together to act as a mood board for creating a piece are still picking up followers and I haven't added anything to them since pinning the finished piece on them. I agree with the DIY, seems anything I pin DIY gets repinned like crazy.
