Hey, we've just added Twitter integration to thingloop. You can turn it on from your Profile using the checkboxes at the bottom, shown above.
thingloop will update your status periodically to let your friends know when you're adding items, etc. Let us know how you get on with it. Note, you can also use it when you are 'shouting out' and asking people if they can lend you stuff. Maybe one of your followers has the thing you need?
