I used to, for my French cycling photos, but only ever got up to about 80 subscribers. Then I started a Facebook Page, have now got 5.7k followers and get about 500k views in a good month, so the blog is dormant - Facebook has an inbuilt facility of sharing and me being able to invite people who have liked stuff that means the reach is far far wider. Oh, and they pay me some money, which is nice... enough that I claim photographic stuff against my tax.
