Hi,
I have created a google plus and twitter account for our activities.
Openstreetmap Israel@GooglePlus
https://plus.google.com/u/0/108321379594865534027
OpenstreetmapIL@Twitter

So if there is anything interesting both in Hebrew or English just let me know.
BTW: I have created a simple Openstreetmap Israel logo. You are welcome to reuse it
