We've just released a new feature on thingloop, which should make it easier to see what sorts of items your friends have got that you can borrow. It can be a bit crazy once you are connected to a few people and there are hundreds of items that you can see, so this should make it a little easier to manage.
In the My Stuff and Their Stuff views you can now see a clickable representation of the most popular item tags. You can click a tag to add it to the item filter. For instance, clicking on the book tag would show all the items with the book tag.
If you are a bit bamboozled as to what a tag is don't worry. A tag is a word that you would associate with an item, to help other people find it. For instance, for your hammer drill you might tag it as diy tool drill hammer cordless. This would help someone find out quickly what drills people are sharing with them.
Another example might be a romantic comedy DVD, in which case you might tag it as dvd film movie romcom, or something along those lines. This means that if someone is in the mood for a romcom they can just pop the tag in the search box and see what movies there are available, without having to browse through all the action, fantasy, scifi, etc, movies.
