[Wikiquality-l] Working on blame tool

[Luca de Alfaro]

The implementation we have in WikiTrust is that when you click on a word of
a version, you are sent to the diff where the word originates.

We have two demos up, and we are adding other Wikipedias to these demos as
our servers permit...

To see the demos, go to
https://addons.mozilla.org/en-US/firefox/addon/11087and install the
WikiTrust add-on.  Then, you can browse the Italian or
Portuguese Wikipedia, and it should work (it.wikimedia.org and
pt.wikimedia.org).

Some notes on this demo:

It is slow, because there is some back-and-forth between UCSC and Wikimedia
Foundation servers.  If this were running at the WMF, it would be way
faster.

Again, as it is not running at the Foundation, we are not notified of new
edits.  So sometimes, we don't have an analysis for the revision you
request.  In that case, we fetch what we need and we analyze the revision.
You should be able to see the results of the analysis after ten seconds or
so.
