Tweecious is a new Firefox plugin that automates the conversion of Twitter links to Delicious bookmarks. Once installed, the plugin checks to make sure you're logged into both services and then parses your tweets in order to post the links you tweet to your Delicious account. What's great about this particular add-on is not only how well it works, but that it doesn't require your passwords in order to do so.

Search advertising network LookSmart and Diigo, a popular web annotation and research tool, announced a new partnership today. Under the terms of this partnership, LookSmart will transfer Furl, its struggling social bookmarking service, to Diigo. However, while Diigo announced this as an acquisition of Furl, the reality is that Looksmart is getting an equity position in Diigo in return.

Delicious, Yahoo's online bookmarking tool, only forces a very loose organization upon its users. While this straightforward method is great for most users, it can often make finding bookmarks harder in the long run, especially when you manage a large collection of bookmarks on the service. Facette, a new MIT project, is trying a different approach. With Facette, you can create a more organized data set on Delicious, as it forces you to be more specific about how you want to categorize each new bookmark.

Opera plans to unveil a new version of its SDK today that will allow Opera's partners to create a more uniform browsing experience across multiple devices and platforms. The new version of the Opera Devices SDK now gives developers access to Opera Link, the company's bookmark synchronization service. Once device manufacturers start integrating this, users will be able to easily access their Opera bookmarks from their mobile phone, desktop, or Wii.

Even though Google took their web browser Google Chrome out of beta last month, we can't help but feel like Chrome is still only half way to being a compete product at this point. Without RSS support, the ability to use add-ons, and gasp! no Mac version, Chrome still has a way to go before people give up Firefox for good and make a full switch.

While the MD5 hack that puts e-commerce sites at risk by faking security certificates received most of the attention at the 25C3 conference in Berlin today, another interesting talk about using XMPP to ensure privacy and security on social networks by Jan Torben Heuer caught our eyes as well. Heuer demoed a social bookmarking service named Diki, which implements some of his ideas, though in the long run, the developers are planning to take this prototype and develop a full-blown social network with a focus on privacy and encryption around this.

It was two years ago that we first heard of Zigtag, a service that promised to "transform how people search, save and share knowledge & information." Now, after a nine-month private beta, this semantic tagging service has finally launched. But is Zigtag's bookmarking tool intelligent enough for 2009?

Earlier this week when we wrote about "The Perfect Social Tool," a commenter on the post hinted that a service called Favo may be it. Curious, we went to check it out. Well, Favo may not be the social tool we were dreaming of, but by all appearances, it does look like something we want to try. Although Favo hasn't launched yet, it appears to be an intelligent bookmark manager that could finally have us ending our relationship with delicious for good.
