On the Delicious blog today, the social bookmarking site has announced a slew of enhancements in addition to the usual bug fixes for their most recent release.

From their interactive graphs to their iPhone-optimized mobile site to their tracking of who shares what items when, Delicious is showing a deep understanding of where the real-time web is heading and how traffic in this environment works. They're giving users and content creators the tools they need to optimize for this environment. Read on for a complete list of Delicious' new flavors.

Search Refinement and Graphing
Refining search results by date is, as the blog post states, "sooo 1995!" Now, Delicious will let users search for results within a limit of just minutes, if they so desire.

They've also added interactive graphs for periods more than 24 hours before the current time. Users can highlight an area on the graph and search for results that appeared within that time frame.

Who, What, Where?
A feature we love is the addition of recipient tags to a user's bookmarks. The tags show what bookmarks were sent to a Twitter account or emailed to a friend.

iPhone-Optimized Mobile Site
iPhone users will now get a richer and simpler bookmarking and link-saving experience. Delicious' post reads, "Use your to:read tag and read all those articles you've been meaning to read. Alternatively, see what's popular on the 'Explore' page or search for whatever happens to peak your interest."

Graphs
The graphs seen on search results pages are now also available on URL details pages and in the revamped Tagometer badges, which will now show the number of saved links over time on a graph.

URL Details
Data on links is now available in a much more digestible format, complete with graphs, of course!

Especially for mobile users and those with social media obsessions, this new suite of features seems to be as useful as well as fun to play with.
