Facebook now lets you create pages for businesses and products, so I’ve created a Facebook page for GigaSpaces. If you want to join it as a "fan" (facebook terminology), just go to the page (click on link above) and on the upper right corner click on "add to my products". We’ll update on new events, offerings, product developments, etc. and you’ll receive it via facebook.
Hopefully, over time some interesting discussions will take place.
