With so many different ways to get information on the web (twitter, facebook, myspace, RSS, etc.), I would like to combine them into one place rather than having to run different tools or visit different web sites. Is there a client (web-based or otherwise) that can combine these varying information sources into a single timeline? Preferrably, this would also allow me to update my own status and to respond to items.
If your sources of information are RSS or Atom based or have RSS or Atom feeds available then you can use Yahoo! Pipes to combine them into a single feed.
You can use Google Reader and subscribe to RSS for each of those sites mentioned. That's probably the easiest way to do it.
If you are still looking try net vibes. This site is really well designed. Just select the social network dashboard and you will be given the opertunity to customise modules (what they call wigets).
