I recently read a great post by Larry Bodine about mistakes lawyers make on LinkedIn.
These are great points as you can see below. The biggest mistake I see is that many lawyers are not on LinkedIn. Primarily smaller law firms and solo practitioners. I recently did a search of Law Practice/ Law Firms for my zip code and only 7 firms showed up with 10 or less employees. Conversly, 185 law firms showed up with 10 or more employees.
Small law firms and solo practitioners should be networking as much if not more than the larger firms. So my recommendation, get on LinkedIn then follow the information on Larry Bodine's blog.
