As a means of dealing with the mountains of spam comments I get, I am (for now) resorting to comment authentication. This means that in order to make a comment, you need to sign in to TypeKey, a free service for such purposes.

I’m sorry for the inconvenience – I don’t like having to do a log-in at another site to post comments, either. But wading through the spam comments is time-consuming, and several times now I have missed a real comment amidst all the spam, which is Not Good. Perhaps we’ll get some more sophisticated automatic system in the future, but for now I’m going to use this.

I gather several other Adobe blogs are going to the same system; at least you’ll only need to sign in once.
