David Warlick explains the three different types of PLNs (Personal Learning Network). 
1.  Synchronous connections are personally maintained networks of people we contact regularly for their input on professional and/or personal issues.  These groups of people have grown due to the removal of traditional barriers such as geography, background, language, and culture.
2.  Semisynchronous connections are personally and socially maintained networks with a "nearly now" time that replaces Real Time.  In other words, you can post a topical question and receive responses from people in a position to be very helpful.
3.  Asynchronous connections are dynamically maintained networks that connect you with valuable sources rather than people.  The primary tool for this is RSS Aggregator such as Google Reader, Netvibes, or Pageflakes.  Using an aggregator is like placing a customized order into a social media network.

Are PLNs worthwhile? 
Yes.  We are surrounded by innovative technology.  Tapping into this area of network technology is an invaluable tool.  Using a PLN can only enrich your teaching experience.

How much time should I spend using a PLN?
The choice is yours.  Use it to your level of comfort.  You will most likely discover that the more you use it, the more you'll want to use it.
