"language editing wars", it would also make the map practicable
for tourists. For example, one wants the map of Beijing in, say,
Spanish, - here you are, select the Spanish language in the
drop-down list. But for this to work the tag: name:es=Pekín should
be present in the OSM database. <br class="">

side rendering sounds like there is one client. But in fact it
means rendering in a browser, or even more correctly in a
rendering engine of a browser [1]. Rendering engines, or for
simplification JavaScript engines, are developed by web browser
vendors, and they differ here and there not only between vendors,
but between newer and older versions, and between operating
systems too. There are quite a few browsers: Firefox, Chrome,
Opera, Safari, Internet Explorer, and so on. <br class="">

work not in one or two, but in all of them, on all operating
systems. What is not a trivial task at all, since client side
rendering depends even more on multiple ever-changing browsers, as
opposite to the current server side rendering, where all the heavy
lifting is done on a single server, which is under control of the
OSM community.<br class="">

<div class="">I don't think its so much being an ESRI fan but more the
hope that we migrate to vector tiles for <a href="http://osm.org/" target="_blank" class="">osm.org</a>.
ESRI is just showing us that it can be done. Vector tiles
can bring a lot of power and customization to the <a href="http://osm.org/" target="_blank" class="">osm.org</a>
site. However, getting to vector tiles will take a
concentrated effort from a group of volunteers. </div>
