Evan and Meg were the actual founders of Blogger. Paul did all the coding behind this site. Blogger is free service to create blogs .It has now been acquired by Google.

Twitter is a social networking and micro-blogging service that allows users to send "updates" (text-based posts, up to 140 characters long) via SMS, instant messaging, email, the Twitter website, or an application such as Twitterrific. Twitter was founded in March 2006 by San Francisco start-up company Obvious Corp.
Updates are displayed on the user's profile page and also instantly delivered to other users who have signed up to receive them. The sender can restrict delivery to those in his or her circle of friends (delivery to everyone is the default). Users can receive updates via the Twitter website, instant messaging, SMS, RSS, email or through an application. For SMS, currently three gateway numbers are available: short codes for the USA and Canada and a UK number for international use. While the Twitter service is free, posting and receiving updates via SMS may incur charges from the wireless carrier. Several third parties offer posting and receiving updates via email.
Odeo is an online application that allows for recording and sharing podcasts with a simple Macromedia Flash-based interface. It also contains a directory and radio, with podcast channels. Odeo was developed by founders Noah Glass who founded Audioblog and Evan Williams, who previously founders Pyra Labs respectively, and received funding from Charles River Ventures.
Initially this was held by both. Subsequently, Williams bought out Charles River's interest in the company, as well as several other investors, and reformed the organization under a new company, Obvious Corp.
Odeo did'nt see as much success as some of their older products like blogger.They neither made any profit nor loss out of this site. It was all a waste of time.
On February 19, 2007, Evan Williams wrote in his blog that Odeo was for sale. Since late March the site no longer seems to have any new podcasts added.
On May 9, 2007 New York-based Sonic Mountain acquired Odeo. Sonic Mountain, in turn, has been acquired by the Amergence Group.
Currently it has a Alexa ranking of 10k+ (10,000+).

Evan Williams, born in 1972, a native of Nebraska, is an American entrepreneur who has founded two Internet companies.
Williams and Meg Hourihan co-founded Pyra Labs to make project management software, but parts of the application were used to create Blogger, one of the first web applications for creating and managing blogs. The company survived despite the departure of Hourihan and other employees, and was eventually acquired by Google.
Williams left Google in 2004 to co-found Odeo, a podcasting company. In late 2006, Williams co-founded Obvious Corp with Biz Stone and other former Odeo employees. Obvious has acquired all previous properties of Odeo, Inc., including Odeo and Twitter, another project started by Williams.
He maintains the popular weblog Evhead.com.
