So I got around to upgrading to Textpattern 4.0 today, and despite some minor hiccups, I think everything is functional again. If you come across any strange quirks, please let me know so I can fix things up. I’m a big fan of TXP, and whil my aversion to PHP has grown over the years, it still seems well-suited to my purposes for blogging. Being able to produce content with textile, inline php code if necessary, and use an easy templating and extension system makes it attractive to me. It’s still not for everybody — I think wordpress is still a far more generic and accessible solution for those that just want a turnkey blog, but I’ve not regretted my switch from a custom solution to this yet.
