Your for: and via: tags on Delicious
Short version: the system:has:keyword is a powerful and little known feature of del.icio.us that can help you retrieve, count and evaluate special tags.
Long version: let’s see two very special urls mentioned on the support forum that delve into the more social aspects of bookmarking at Delicious.com.
You can try them by just swapping ‘account’ with your own username (if you have one, that is).
delicious.com/account/system:has:for
Explanation: this url will show all of the bookmarks one has forwarded to other del.icio.us users with the official “for:” tag and will also show the grand total (1076 in my case).
Usefulness: you can check which how much bookmarks you have spamm^^ forwarded to people in your network.
delicious.com/account/system:has:via
Explanation: if you use the unofficial this url will show all of the bookmarks one has “credited” to other del.icio.us users and will also show the grand total (around 290 in my case).
Usefulness: you can do a search on which and how many bookmarks on any topic you have actually got from other del.icio.us users and hence also the usefulness (to you) of its social networking features.
