Yes, it works. Perhaps it's a tiny bit slower than expected but the new h3raLd.com seems to work.
I'll probably find some new exciting bugs to fix in the next few hours, as usual – that will be annoying but perfectly normal.

The good thing is that the new template seems to load faster, mostly due to the fact that I hardly used images ← [not true, te new site appears to be slower, maybe not due to the images], at any rate, let's see how it goes. I can imagine I'll have to implement some sort of caching system for the tagging system in particular, but fortunately CakePHP apparently comes with a built-in caching mechanism for views, models etc. etc. although the documentation available seems to be scarce at the moment, and I've been to lazy to investigate any further.
