I stole the little thumb tack from my brother's blog, changed the color (a little) and incorporated it into my Blog. When in doubt, borrow. This will make it easier to cross-reference my items. The thumb tack points to the archived version of the post in question so even when the item disappears from the main page, I can still link to the original item.
If you wish to link to any of these items, link to the URL that is wrapped around the thumbtack at the foot of each posting.
