This week LinkedIn added the long desired group search feature.
Group searches now allows LinkedIn members to find appropriate networking groups more easily, as members can utilize a "Google-like" keyword search (within their extended networks only).
Previously members had only good chance or the work of individually searching out the details of other professionals' LinkedIn profiles just in order to find existing and appropriate networking groups.
Jason Bailes LinkedIn group search using Google custom search is still useful, and skilled users would use both to keep up to date.
The great part about the official LinkedIn group search is that group membership seems to have drastically increased. Lawyers are not only joining legal networking groups, but they are using them to enhance many of the great features of LinkedIn.
