A blogging trick I just taught myself

This one is for bloggers. Let's say you post an entry that refers back to a previous entry, as I did here. And let's say you want the older entry to link forward to the newer entry. You could manually edit the older entry to add a postscript link to the newer entry. But today, one of those cartoon lightbulbs lit directly over my cranium: Why not send a trackback to the older entry, and let the software generate the forward-looking link? As explained here, we normally send trackbacks to other blogs. But is there any reason why you can't send a trackback to your own blog? On TypePad at least, there isn't.
