I've gone and done it and set up my a new site, called <pudge/*> (pronounced "PudgeGlob").
I won't be fully retiring my other journal sites -- I'll still post Perl stuff on use Perl, for example -- but in general, I'll be using the new site for everything. When I do post something to my other journals -- or to Flickr, or YouTube -- it'll be mirrored there. I've already prepopulated it with thousands of posts from my other sites over the past 10 years.
At some point I will be more closely integrating PudgeTunes with <pudge/*> -- each song will have its own entry, and I'll generate podcast feeds directly from the new site -- but other than that, it's pretty much set.
So now you have one place to go for All Things Pudge.
