If you blog on Blogger, I’m highly unlikely to comment there.
Why? because if I choose anything other than my Google profile, I am not given the option to subscribe to comments, which means if you reply to my reply I simply won’t know about it.
I don’t want to comment on blogs using my Google profile. When I comment on blogs, I want to comment as a blogger – and my blog is on WordPress. The option is there to comment using my WordPress identity, but as soon as I select that option, the box for subscribing to comments disappears.
So, if you’re on Google+ and you post links to your blog posts there, I’ll comment there. If you aren’t – I don’t know, I really don’t.
And no, it’s not your fault that Blogger has this annoying setting.
fwiw, on WordPress you can subscribe to comments on a post no matter which identity you choose to use. just sayin’ :)
