Ever wanted to collect all your web content under one web hub or portal? Is Yahoo Pipes too complicated for you and you want a simple way of gathering your web contents from weblogs, social networking sites and bookmarks? Onaswarm is the best solution I’ve encountered so far.

Onaswarm is a new web service which is currently in beta stage. It lets you collect web contents from your various weblogs, social networks, photo sharing services, social bookmarking sites, e-mail and dump all of these content into one web hub which full searchable indexed and tagged portals called lifestream.

Don’t be misled; Onaswarm is not just another aggregator. Onaswarm aggregates your content just like other RSS aggregators (Bloglines, Google Reader, etc.). But what sets it apart from the usual feed aggregators is the fact that you can create a swarm composed of lifestreams covering the same topic of interests.

And there's more: go read the whole thing.

Thank you very much to Leslie Poston for this verykind(pre-Christmas) review of Onaswarm at Profy:

Have you been looking for a place to put all of your Web 2.0 information? A solution to the pressing need to keep track of all of your social networks, RSS feeds, photo streams, calendar items and more? Look no further, OnaSwarm is here.

I've seen a few other Web 2.0 solutions that have claimed to offer the same "all in one place" Web 2.0 service, but OnaSwarm is hands down the most comprehensive. It offers a way to keep track of as many social networks, feeds and accounts as you want. Imagine - all of your Web 2.0 identities all in one convenient place.

There's a lot more than that; go on over and have a read.
