Developers' Blog comment format system is a PITA, i.e., not at all user friendly.
Since the switchover in commenting systems in the developers' blog, when there are more than a relatively small number of comments the system is a PITA to use. The user has to repeatedly click on "See More" at the bottom to view all the comments, and if they themselves have commented, it can mean having to scroll down and repeat the process a number of times. If one refreshes the page or clicks on a comment link without opening another tab, the whole process also has to be repeated upon return. Then there's knowing where to return to continue reading in another session, now that there are no markers such as page numbers, as there were in the previous system. Opera developers encourage comments, but have set up a system that is a truly cumbersome. I would think they could do a whole lot better than this!
Yes, to all.
And this forum has its own usability problems.
How about going back to usenet with a decent newsagent?
