I do notice myself tagging more after I start to use trunk.ly daily. And I agree that "tagging" is a great to do attach personal opinions on a link. Trunk.ly can import delicious tags. We'll soon add the ability for you to add a tag to your link as well. Having said this, we found most people do not tag, they just search what they want and continue with their life. Based on the existing user behavior data we have, 1% people clicks tag in two weeks. 7-10% uses search at least once.
