Yes -- two of them, one of which I chiefly write and one of which I contribute to. The former is about books (which I like reading) and writing (which I like doing), and it's at
http://jseliger.com . Now I'm one of the perhaps ill-advised souls in English grad school, so some of the material on it might eventually make it into papers. Occasionally I find other interesting book people too, which is an added bonus.
The other blog, Grant Writing Confidential (http://blog.seliger.com), is about my family's business, and it serves a couple of purposes: 1) it signals to clients that we actually know what we're talking about, 2) it brings in search engine traffic we'd other wise not get, and c) we get a chance to write about our work, which virtually no one else understands.
So in both cases, I write for a mixture of business and pleasure.
