Why did I switch, let me count the ways...
Actually there aren't really any solid reasons, which is strange. I was getting peeved with fighting off the comment spam. I realise that there are more agressive actions I could have taken but I think that I also fancied a change.
I never really sampled other blog software as wordpress was the first I switched to after I abandoned my home grown version.
I remember now also feeling that there wasn't much separation of the code from the html, I'm not a fan of having php inbetween the html and prefer to use a templating system.
My love affair with textpattern is that, it isn't a marriage and I might return back to wordpress as txp has it's own faults.
So as you can see, I'm still somewhat confused about what's best. I'll shutup now.
