Opera was one of my most unique customer in my entire carrier. I visited their HQ many times during at least 3 yrs in Waldemar Thranegate. I fell always welcomed and looked forward to go back and meet my friends at Opera. A very special company going against stream. Nothing was impossible for these guys. Best of luck to all of you.
@andrew84 Yes, that's possible, but first the current solution would have to be re-built to allow linking to an arbitrary comment through a blog post. Currently we only render 10 most recent comments with ability to manually show older comments - this would have to be changed in a way that automatically loads relevant portion of the comments thread that includes the comment you are linking to.
We'll try to achieve that when redesigning the solution to support tree-like view, so if anything, this can be implemented afterwards.
