Hi,
you are probably not familiar with this site, but Amud anan (Pillar of cloud) is one of my best sites to spend time in. It is a navigation site, but it is no more than a topographic map of Israel, that one can mark interest spot on it. And when any one can do it, the amount of knowledge sums up to a massive information archive! 
The name is as the Pillar of cloud in the Bible that guided the Israelis to the Promised Land protected during the Exodus (Exodus 13:21–22).
In the long nights I set down in the Technion Student house and sell tickets to Salsa evenings, I used to spend my time when I did not have the mind to study in those small of the night. No, there was Facebook back then… 
Now I find kind of the same type of site for the city of Tel-Aviv 
. Unlike Jerusalem, in which I grow and raised, I know little of the interest buildings in Tel-Aviv. More than that, most of the buildings in Tel-Aviv does not have the houner to hold a Wikipedia article. Unlike the building in Jerusalem, especially in the old city of Jerusalem.
This site is the Tel-Aviv 100 – Municipal encyclopaedia map, and now days I spend much of my spare time (00:00 till 01:00 I mean… 
) going over it reading and learning about sites in the city. I especially looking for sites related to rebellion movements (Haagana, Etzel and Lehi), so I can make a post similar to the one I did (here) about the rebellion movement signs in Ramat-Gan.
