I have mentioned PubSub several times over the past year — it is a terrific way to keep up with information on the Internet, without having to constantly check resources day after day. Once you set PubSub to monitor your keyword searches for you, all you have to do is wait for the results to roll in. Last week Chris Sherman wrote on PubSub in Managing the Firehose of Real-Time Information. PubSub monitors nearly 6.5 million Internet resources — how can you afford not to be using it?
