I'm noting Yahoo's acquisition of the social bookmarking pioneer del.icio.us. This significant Web 2.0 event highlights the growing importance of user-generated tagging and community-driven content organization during the mid-2000s.
I found Trend sweet trend, a useful tool for tracking recent bookmarking activity on del.icio.us. It visualizes popular topics and links, providing a snapshot of what is currently trending across the social bookmarking community.
I found a tool that organizes your del.icio.us bookmarks into clusters. It uses specialized search technology to group similar tags and topics together, helping you navigate and find structure within a large collection of saved links.
I built a tooltip feature that displays popular del.icio.us tags when hovering over links on my blog. This lets you explore related content on del.icio.us by clicking the tags, and I've fixed display issues in Firefox.
I automate my daily reading by matching del.icio.us tags from URLs I've blogged about against trending bookmarks. I score sites based on tag frequency and rank the top five, though I need better APIs to scale.
I'm looking at the new Yahoo conversations site and the latest features in Yahoo Messenger. The update adds support for webcams, message archives, and file sharing to their instant messaging platform.
