Curiosity — who is visiting this blog???

Normally this blog gets a very small number of views per day — in the range of 5-20.  Saturday it got 182.  Today it has 87 already.  This seems quite odd for a blog that hasn’t been updated in weeks.  Another odd thing is that on these days there are no “referrers” listed, and only a tiny number of searches resulting in a handful of page views?  So… who is suddenly reading this site so much?  I assume it is some kind of web crawler and not really 100+ new readers, but if you’ve recently found my site, and want to tell me how, I’d be quite interested in the solution to this mystery!
