I just found the gwan topic interesting and the blog posts even more so.
To eliminate any sort of crazy conspiracy theories, I am in no way shape and or form associated with gwan,nginx,msql,mongodb ect ect.
I enjoy using gwan for my projects. So far my stack is usually nginx+gwan+mysql+mongodb.I use nginx for it's modules and it's PHP support. I use gwan to write C scripts and which is basically the original PHP scripts just converted to C for way better performance. I'v used PHP for a while now so much that I have grown to absolutely hate how slow it is. Still, PHP is easy to dev with so I keep it in my stack.
Also i did not rename the topic someone else did as stated in one of the first comments by the person who actually did the change.
That being said you are incorrect on your first point "submitter renamed it" and paranoid on your second "Coincidence?".
I usually post about gwan that being only 2 topics so far because it just so happens to be my current interest in my field of work.
