Blog Selective Hacks
One of the biggest problems of simple hacks to the system is that they occur system wide, e.g. if you hacked the entry page to specify a default category, that category would become the default for all blogs on the system. This tutorial is a simple hack that will allow you to test the blog_id value and then conditionally display.
Open up lib/MT/App/CMS.pm and search for
my $blog\_id = $app->{query}->param('blog\_id');
and add underneath it
my $blog\_id = $app->{query}->param('blog\_id');
$param->{"blog\_id\_$blog_id"} = 1;
Save CMS.pm and upload it to the appropriate location. That's it, now in your *.tmpl files, you can check the blog_id like so
my $blog\_id = $app->{query}->param('blog\_id');
$param->{"blog\_id\_$blog_id"} = 1;
<TMPL_IF NAME=BLOG_ID_1>...</TMPL_IF>
where the contents of the IF will only display if the blog_id of the blog is 1.

Without a doubt, my default category hack has this problem. To be fair, though, it's still a step up: in my most-used weblog I have a default category set, and in every other weblog, I still have to select a category. In other words, it's no more difficult than before.
I'd also like to point out that using the edit_entry.tmpl and JavaScript to do this has the added benefit that--when upgrading CMS.pm--I don't need to worry about re-implementing the hack.
Yesterday I was contemplating exploring this problem with JavaScript. I should be able to parse the blog_id out of the URL and display a different default category for each weblog based on that. I think.

Jeremy: Thanks! :)
Dan: I'm not sure I understand what you mean, you can have multiple ifs so that you can set a default category for each of your weblogs, using the method you described, it would look something like this
does that answer your question? You're right about losing the hack once you upgrade CMS.pm, this would be a good BigPAPI plugin

This is the hack I'm looking for, but I can't find the correct line in CMS.pm to edit in version 3.3

I found it! In MT3.3 in CMS.pm, it's in the subroutine: build_page underneath the line:
my $blogid = $app->param('blogid');
