If your blog has one of those "Comment as" buttons just after the comment space, don't expect any comments from me.
My comments on your blog disappear into never-never land, no matter which type of ID I choose. Even "Name/URL". Even "Anonymous". I have never been able to comment on any blog that uses this type of comment form. (Blogs with "Choose an identity" work fine.)
I can't figure it out. There are plenty of other comments, so those people didn't have problems. It's just me. Only, it's not just me - I've found a few other folks wandering the internet in search of a solution to this problem.
But I haven't found a solution. Let me know if you have any suggestions.
