Social timelines are going mainstream (see AOL/Bebo), but startups are pushing them to the next level. Today, Lifeblob, the Indian startup working on ways for you to visualize your life on the net, is introducing a refreshed version of its social timeline creation tool. With it, you can easily patch together a visual representation of your life’s most memorable moments by timestamping certain events and enriching them with photos, text and videos. The end result can easily be shared on a variety of social services, or embedded into any blog or web page (example below).

It’s an invite-only service for now, but we have an unlimited amount of invite codes for you. It’s simply techcrunch and you can use it to sign up here.

Lifeblob is one of the investments of SeedFund, the Google-backed VC fund who actively looks for early-stage financing deals within the Indian startup community. The company raised its first round of financing of approximately $1 million from the fund in August 2008. It employs only 4 people for now and its business model is centered around advertising – which it will start rolling out after its general launch – and premium services (like branded timelines, etc.)

Want to follow every Tweet, blog post, YouTube video and Flickr photo put out by the Obama or McCain camps? Now you can follow the campaigns in a handy Dipity Election Center timeline. Using its latest Dipity 2.0 timeline mashup, the Election Center places each entry on a timeline that you can scroll through. Click on an entry, and a box opens to show you more detailed information. You can also leave a comment.

Each timeline can be embedded as a widget anywhere on the Web. And you can see everyone’s comments from any widget. The idea is that Obama supporters will put the Obama widget on their MySpace page or blog and that McCain supporters will do the same on theirs. I’ve embedded both widgets below. You can see by the larger number of entries for the Obama campaign that it is making better use of social media to get its message out. (At least that was the case when I looked at the timelines—see screenshot).

Dipity, a timeline-based lifestreaming aggregator, has launched its 2.0 release to the public. The new release includes a variety of new social features that have turned Dipity into a viable alternative to FriendFeed and other lifestreaming services, as well as a replacement for standard RSS readers.

Dipity revolves around powerful timelines built in AJAX, which intuitively display content like blog posts, YouTube videos, and Flickr photos in small hovering rectangles that can be expanded. The site is very well designed, and while the timelines seem to lag occasionally when they refresh, they’re fun to play around with (and if you don’t like the timelines, there are a few alternative views).

The service itself should be familiar to anyone who has used FriendFeed, SocialThing!, or any number of similar sites. Users are asked to input their account credentials from services that include Flickr, Picassa, and Twitter, which are used to populate the timeline. Beyond these, Dipity allows users to automatically monitor keywords across services like Digg and YouTube (you can have new Obama videos automatically appear in your timeline), and RSS feeds.
