"PubSub is a 'matching engine' that offers a promising new way to keep up to date while alleviating information overload."

"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?"
Tom Mighell, Inter Alia Weblog

"If you're not using a tool like PubSub to see what's being said about you and to monitor your company and brands, you're behind the times."
