Okay, folks. Seems to have worked…so far.
And because this is the first thing I wanted to be able to do: let's talk tags.
The UTW importer seems to work very well–although, come on, guys: UTW was a good plugin. Do you really have to refer to it as a "nasty habit"? Kinda tacky.
Anyway, it zapped my 500-some odd tags fairly quickly. There were four very odd errors where it appears tags didn't make the leap–some sort of database error–but I didn't take down the error. If I see it again, I will.
But here's the part that's a little wonky–and a little unnerving. There's nothing in the WordPress admin area to let you tinker with tags. They're just sort of there. I understand there's some plugins to help the tag admin thing, but as long as it works, I don't care.
I had to strip the UTW code out of my theme because it was causing errors (and of course, reactivating the UTW plugin caused a fatal error which WordPress mercifully put the kibosh on before it could do any damage). So how to get the tags back in?
Well, this post is a good start, and the followup's not bad, but what if you just want to say something witty and then list your tags in a comma-separated list? It's not obvious.
< ?php the_tags('Taggification: ', ', ' , ''); ?>
That's how I do the tags on this theme. And as for context of where it goes?
< ?php the_content(__('(more...)')); ?>
<br />< ?php the_tags('Taggification: ', ', ' , ''); ?>
<p>Filed under: < ?php the_category(' and') ?>
<br />Comments: < ?php comments_popup_link(__('None'), __('1 Comment'), __('% Comments')); ?></p>
Tinker with it till you get it to look like what you want.
I'm going to be changing themes anyway. This one just looks like a giant nasty kluge.
