Getting the links over here into the post over there has always been something of a blogging chore. Not anymore; the bundle makes it easy. Simply open a Safari (or Chrome or Firefox, but there you’ll need a separate extension to copy the tabs) window and get all your necessary links into tabs in the frontmost window. Dash back to TextMate, hit the trusty ^⌘w and choose Tabs to References (Safari). In the heads-up display, select the tabs you really want to include (use shift or command to batch-select), and when you’re all set hit OK.
The reference list pops in at the top of your post; to use them, simply highlight your target text, trigger the menu and choose Link to Reference.
