As this change has been in effect for a few days now I have really noticed the way it has changed the way I use WordPress.
I used to do my blog housekeeping then go to the comments I've made page and not resurface for quite a while. I would be following comments, adding new ones, and following threads to new blogs or posts that were part of the whole coversation.
Now I do my blog housekeeping, read my regular blogs and then it feels as though my trail of interactions is bought to a conclusion. That feeling of diving into the community via the 'comments' page has gone. Now, going to the reader and seeing my own comment floating about, unattached, to the conversation doesn't inspire me to click on other posts or look at new blogs (if it works, very slow internet here).
I find myself walking away from the computer to do those things I should be, rather than wasting my spare time on WP. (I guess I should be thanking you for this change rather than being annoyed then, shouldn't I?)
If this change is a permanent one (and, sadly, I am convinced it is) can the other comments made on a post after our own be available? Perhaps as a sideways 'see comments' menu like the way the orange notification button works?
I don't really care to read my own comment again, I know what I said, but it is what others have said that really interests me.
