I've switched the setting on my blog (largely inactive though it might be) to not allow anonymous commenting. I regret having to do this, but recently I've been getting a number of off-topic anonymous comments that are phishing or just plain weird. For example, I posted a while back about going through a "dry spell." I was referring to a lull in my blogging. Apparently someone (more likely some bot) interpreted that as a bedroom reference and I ended up with several postings related to--how shall I put this--men's pharmaceuticals. I suppose it's funny, but I'm not laughing.
I hope this doesn't exclude anyone who wants to post because I enjoy and value your feedback. You can still post if you have a Google/Blogger account or via an OpenID user name (i.e., Yahoo, etc.) and you can reach me directly through email.
