Make news and info come to you and enhance perception of the depth of your specialty.
You may already subscribe to blogs, but do you subscribe to "searches"? Subject search results can be amazingly informative.
Using Bloglines or another blog aggregator, search (top right of page in Bloglines) for key words related to an important client’s or prospect's industry (e.g. tool and die, over the road trucking, funeral homes, veterinary services, apparel, importing, etc).
Add the search results to "your feeds" and skim for five minutes per day--occasionally forward items of interest to your client.
