Mozilla Labs has launched a new "lifestream" platform called sudoSocial. Pulling its name from the Linux command "sudo" which allows users to run programs with other, usually elevated privileges, the sudoSocial publishing platform aims to give you both access and control over your many online identities.

Although sudoSocial would be suitable for curating any stream of content, explains the introductory blog post, in its early, still rather sparse format, it's better for personal homepages that aggregate your various feeds, like Flickr photos and blog posts, for example.

Twitter just launched an updated, more dynamic homepage. The old, static homepage that didn't really explain how Twitter really works and just showed a list of trending topic and a search form. The new homepage, on the other hand, features a scrolling list of trending topics, a constantly updating view of tweets from popular Twitter users, a random sampling of suggested users and a new explanation of what Twitter is.

A visit to the typical homepage for a venture capital firm most likely provides a well designed landing page that spells out the firm's mission with links to its portfolio companies and VC bios. Secondary to this general information is a page dedicated to press releases from the firm, or in many cases, a company blog with relevant posts. First Round Capital, however, recently redesigned its homepage to place a much heavier emphasis on real-time information from news sources and its VCs, and portfolio companies.

Today, Yahoo!Mobile SVP David Ko introduced the company's new mobile homepage calling it "the world's most advanced mobile homepage."

At once rich and simple, the new homepage is accessible by more than 1,900 different mobile devices, which Yahoo! says represents a 500 percent increase since the mobile site launched in April. We checked out the site on a BlackBerry Storm tonight and were impressed by the features Yahoo! is offering for discovery and filtering of content. From tech-related videos to dynamically refreshed news feeds, Yahoo! gives mobile users plenty of room to play.

The Yahoo! Developer Network blog has a post today calling for "innovative and flawless" applications to be submitted for inclusion in a gallery section on their redesigned homepage.

Apps are to be built using Yahoo!'s proprietary development platform, YAP. The YDN post further noted, "We're working on an array of additional developer monetization opportunities - these will be available soon." The gallery's inaugural class includes YAP-built applications from Mint, Lumosity, Flixter, Target, and WordPress.

Google just received a design patent for Google Search's homepage. It took the US Patent Office over five years to approve this patent (D599,372) for the design of a "graphical user interface for a display screen of a communications terminal," but Google's request was finally approved yesterday. The company already owned a patent for its search results pages. In addition, Google also received a patent for a server-based spellchecker yesterday, as well as another one for "collaborative web page authoring."
