Notify.me – This is a notification service that alerts you of any new content that’s added to an RSS feed. I’ve used Yahoo! Alerts, Yotify, and Google Alerts prior to testing and I can say without a doubt that Notify.me beats them all hands down in terms of the least amount of lag time. Using a test blog I measured the elapsed time between the instant an article was published to the RSS feed and the actual time the notification was received from Notify.me. In three separate tests, Notify.me alerts were delivered within one to four minutes after publishing. This is extremely fast in comparison to the others listed below and why Notify.me is an excellent tool for following favorite blogs for which you are interested in commenting as well as other feed based content that is extremely time sensitive. Notify.me can be used for other things such as tracking items on eBay or Craigslist, receiving automatic notification of new job posts, following breaking new stories, and much more. Alerts can be sent to you via SMS, email, instant messaging, or via Notify.me’s own Adobe AIR application. Read more »
