This post expands upon a talk I gave recently about using blogs as an academic research and thought development tool.
Identify interesting people in your field of study
Academic research is one part original thought and ninety nine parts identifying the limits of existing knowledge. This task can take up a good part of your time and when it comes to the Web identifying movers and shakers in your field can be frustrating and highly unproductive task.
Online communities: social networks and newsgroups
The first place to start when identifying interesting people in your line of study is the various social networks and interest groups on the Web.
As far as social networks go arguably the two most productive for finding people are Facebook and LinkedIn. Whilst Facebook is aimed at the casual user there is a diverse range of interest groups forming around nearly every topic imaginable. Don't despair at the variable quality of the content within these groups, the fact you are almost always dealing with real people makes the effort needed to browse through these groups worthwhile. Likewise whilst the business-centric LinkedIn lacks Facebook's group capabilities you'll be surprised how many people in your extended professional network share similar interests or could be of benefit to your research.
At the more traditional end of the spectrum newsgroups like those at Google Groups and Yahoo Groups are good places to to find clusters of people interested in your research. Most newsgroups are welcoming to newcomers, especially those that have something to offer, but it pays to passively monitor potential groups for a while in order to properly gauge the tone and style of the people involved. Whilst it may seem easy to charge straight in, it is hard to rebuild bridges if you start things off on the wrong foot. For example it is not good karma for your first newsgroup posting to read "can someone tell me everything about subject X".
Social bookmarking
There are a growing number of websites dedicated to storing and sharing your Web bookmarks.
The most notable of these is del.icio.us but there are others such as Diigo and Simpy that are also very good.
These online repositories assist your research by helping you find people with similar interests as yourself. This is achieved by browsing through the 'tags' people associate with their bookmarks, whilst some services can even recommend people who appear to share similar interests as yourself. Social bookmarking can also act like a human powered search engine by enabling you to track popular or new bookmarks on a specific topic. However the drawback of social bookmarking is that for the system to function at its full potential you must publish your bookmarks for the world to see. This maybe a problem if privacy is an issue with your research or you just don't like the idea of being 'on show'.
