What do you mean by a "windows download"?
I got a gzipped tar file. In it was a Python program, two HTML files, a JavaScript file, and a few other files. The Python script didn't run because I don't have the 'screenlets' packages installed, and the HTML used OpenLayers but only displayed "More OSM coming soon..." tiles.

Stupid spam

It seems to have all been removed now. Clearly something needs to be done about spam now.

Wow, now that's some spam!

So very spammy. A simple Bayesian filter would have picked this one.

Were the comments always closed on that post? I wonder what sort of responses this idiot got.

It's just a scare piece from a Washington lobbying group.

But I've never viewed that part of the OSM map before I followed your link. So I can't have had those tiles in my browser cache. The OSM server gave me old tiles, then gave me new tiles when I shift-reloaded them. Was this because it took the server longer than 3 seconds to render each new tile, as amm described?

I checked that first link. Indeed "Enes" was on its own. Then I switched through the different renders and it showed up as a building (except Cycle Map is blank for some reason). I switched back to Mapnik and it then appeared as a building.

The funny thing is that I closed the tab, reopened it, and had exactly the same experience. I've since opened the individual tiles in my browser:

They initially showed no building. I did a shift-reload on each and it appeared. They then seemed to be 'permanently' updated in the slippy map. Something funny's going on with the caching of the tiles.
Note, I'm using Firefox/Iceweasel 3.5.6, behind a Squid 3.0 proxy.

The discrepancies are interesting. Perhaps the positions are made in relation to the Australian Geodetic Datum (AGD66). Australia is moving north-ish at something like 5-7 cm a year, but it would take well over 100 years to move 8-10 m. So I'm not sure what could be causing it. Maybe it's just laziness or sloppiness.
