OmGah, I don't know why I ever think I can figure this stuff out myself. Some themes are just plain difficult.
I know Asides aren't that interesting to folks now, since Matt Cutts introduced them a good 6 years ago, but all of a sudden I decided I would like them in one of my blogs, as a way to break up the look of the page, and also to add a quick link or shout-out.
My theme doesn't really support them. Or rather, the paid version of Ascetica does, in wordpress.com, but not in .org. After a week, I managed to add it to the formats in functions, so it now shows up on my admin post page, as a check box when I want to write one. (add_post_type, from http://codex.wordpress.org/Post_Formats)
However, I have not figured out how or where to add get_post_format, to actually strip out the title, and make it an aside, and not look like a regular post. Add post type is in Function.php, but get_post_format looks like it's in home.php, for some reason.
Can someone please just give me code or tell me where to put it to bring up an aside with no post title?
