Always nice to have a discussion exploring things we agree on.

I realise that my use of reliable might have misled:- I was not talking
about network reliability, but link and coreference reliability.
To put it another way, can I move through a few of the circles, following
the arrows, and end up finding something I expect and is useful.
For example, long ago, the first thing I tried was to get photos of people
by going from dbpedia to flickwrapper - I just couldn't do it because
although it was usually someone with the same name, it wasn't the right
person.

But I do think we have a strong agreement that the challenge is to consume
the data - I just think that when that happens more extensively people will
discover that the data is worse than they think.
And yes, fit for purpose can only be judged in use for purpose.
