I missed this the first time around and was glad to see it back. Gravitec is a great way to maximize the value of the people coming to your site and get them to return. I like that it's flexible, so you can not only announce new updates/products, but also recycle traffic via RSS automation, meaning that it's a great tool for podcasters and bloggers.

Setup is fairly straightforward, especially if you have Wordpress. Gravitec will work on any site though. I installed to my site via Google Tag Manager, which is a nice option.

Overall, a really good experience so far. Definitely take a look at it, if you want to take advantage of the traffic you already have and bring people back around to you.
