There's now a RSS feed for items you post via Little Pork Chop.
Here's an example feed, the one for my test account. You can see there are already a few items in the feed.
Click the gear icon in the left margin.
Click the Feed panel.
You should see a set of preferences for your RSS feed. Change the defaults if you like, or just click OK to accept them.
Post something via Little Pork Chop.
Go back to the Feed panel. Now you should see a Feed URL filled in, in the last entry. That's the URL you should subscribe to in the feed reader, or give to your friends to follow.
