• Six ways Gmail revolutionized e-mail – CNN.com – Thursday marks the sixth birthday of Google's pioneering e-mail service: Gmail.
• Our Choice: The Funniest April Fools Jokes – It’s that date again, folks. If you’ve seen an amazing new service or something that sounds too good to be true, it probably is — very few companies take April 1 seriously. Reports of April Fools jokes are pouring in; as we do every year, we’ll mention the ones that are either very funny or amazingly clever.
• April Fools 2010 From Google & Others – Today is a worst/best day for journalists or bloggers, depending on your worldview: April Fools Day. Many technology companies come out and try to fool people with fake or funny news. Below is a collection of, what appears to be, April Fools Day hoaxes from Google and other search related companies for the day. I do hope to continue to update it throughout the day.
• Q&A: Personal vs. Professional Branding in Social MEdia – Dan Schwabel is not only a personal branding expert, he’s someone I’ve come to know and respect over the years…and definitely someone I consider a friend.

• TweetDeck Taps TwitVid For Video Sharing, Replacing 12seconds – TweetDeck is switching its default video Tweeting platform today, from 12seconds to TwitVid.

• Unvarnished: A Clean, Well-Lighted Place For Defamation – Today, Unvarnished makes its beta debut. It’s essentially Yelp for LinkedIn: any user can create an online profile for a professional and submit anonymous reviews. You can claim your profile, but unlike LinkedIn, you have to accept every post, warts and all. And once the profile is up there’s no taking it down.
• YouTube Blog: Latest Changes to Video Page: New Playlist Experience, Integrated Comments & More – The video page overhaul that's underway now is one of the biggest redesigns in YouTube history. It's been a month since we offered a sneak peek of the new look and functionality, and in that time we've been gathering your feedback, looking at data, and tweaking elements to ensure that the page is as clean and useful as it can be.
• YouTube Blog: The Video Page Gets a Makeover – From the Queen of England to the queen of your 'hood, from aspiring filmmakers to Hollywood studios, from high school graduation videos to citizen reports of revolutionary moments in Iran, it all has a home on YouTube. This creates a really big challenge: how do we design a site that reflects so many different users, experiences and videos? This is a question we've thought about a lot since we launched in 2005. The result of some of this thinking (some might say over-thinking) is a video page chock-full of features that reflect a lot of different things to a lot of different people, but can feel cluttered and a little overwhelming. We've spent a lot of time over the last 10 months asking ourselves some tough questions about this page and posing some of those questions to you in blog posts, roundtable discussions, one-on-one conversations with the community and even on forums like our Product Ideas for YouTube page
• YouTube To Roll Out New Design For All Video Pages Today – A YouTube partner just forwarded us an e-mail he received from the Google company, stating that all videos will be transitioned to the newly designed page some time today.
• Less Than One Third Of Tweets Come From The United States, Study Says – Paris-based Semiocast, which helps brands understand and interact with real-time Web services, has again done a study on Twitter usage. After finding that only 50% of tweets are in English, based on an analysis of 2.8 million tweets, the company has now looked at nearly five times as many Twitter messages in order to gain more insight on the increased international presence of the popular micro-sharing service.
