When PR agencies encourage corporate executives to engage in public dialogue, they tell them to "embrace the chaos". As of today, chaos has a measurement API, and its name is ContextVoice. Romanian SeedCamp winner UberVU just launched ContextVoice in the hopes that inquisitive companies will "track the web's conversational graph". In other words, we're about to see a smorgasbord of brand commentary and all the social media trimmings will be there.

There are a slew of social media aggregation sites willing, waiting, and wanting to pull your updates, videos, photos, links, music, "shares," "likes," and other content from all around the web. A few of them work well, some have really cool features, and others have critical mass.

But none of them are as drop-dead good-looking - or as customizable - as AmpliFeeder, a free, open-source distributed social activity aggregator. The only major drawback: It's the kind of web app that needs to be installed on a server. But a hosted version is in the works, and the screen shots prove it's so worth the effort.

Love it or hate it, but there's no arguing that the go-to aggregator for finding the top tech news of the day all on one page is none other than the news portal Techmeme. It's the site that catches you up when you get behind, lets you know what happened while you slept, and tracks the buzz (and yes, the echoes, too) of the tech blogosphere. Other competitors exist, but no one - not even Google - seems to be able to compete.

So why even bother covering yet another Techmeme wannabe? Because competition is important. Techmeme may do a great job, but innovation can still be found elsewhere.

Streaming themed tweets in such fascinating verticals as journalism, venture capital, and music, Twitter aggregator SawHorse has raised an undisclosed seed round to support its growing network of sites.

Its two newest sites are focused on pets and celebrities.
