Fine with me.

I know.
And previously you have agreed to stop calling it a "LOD Cloud cache", since it isn't.
And then you slip back into it, and then we have one of these discussions :-)

Of course, it is a great resource, both technically and in terms of maintenance, and very useful.
A powerful service to the community.
And might be just what Annika wants.

But there are, for example, wrapper (and aleph-0 size) sets.
So people who come to your site and expect to find the URIs from them will be seriously misled.
In this sense, it is like caching the web, with all the problems of the hidden web.

As I say, great work, but please don't mislead people by suggesting that it has all the URIs in the Cloud.
