== Commentary ==<br />
FWIW, MarkABaker [http://www.markbaker.ca/blog/2006/08/09/sparql-useful-but-not-a-game-changer/ didn't think this list will get very big in the long run]. He seems to have been proven wrong, so this comment has been moved to the bottom....<br />
<br />
Mark responds; wrong? Well, this is hardly the long run, but ~40 endpoints might as well be zero on the scale of the Web. When you get a few million, drop me a line 8-)<br />

== Commentary ==<br />
FWIW, MarkABaker [http://www.markbaker.ca/blog/2006/08/09/sparql-useful-but-not-a-game-changer/ didn't think this list will get very big in the long run]. He seems to have been proven wrong, so this comment has been moved to the bottom....<br />
<br />
Mark responds; wrong? Well, this is hardly the long run, but ~40 endpoints might as well be zero on the scale of the Web. When you get a few million, drop me a line 8-)<br />
