Yes, I use them on TrueSchool.me. It's basically a straight blog with whatever creative work I've posted (photos, songs, design projects) at the top. I use a sticky post as a pseudo-landing page to introduce the blog so people know what they're looking at right when they arrive.

I also used to use them with the Path theme on my main blog, TedCurran.net, because that theme would automatically make a featured carousel out of all the posts marked "sticky". I have a different theme now, so it's not up there anymore.
