One thing I find peculiar is that adding a text somewhere can lower the trust of the surrounding text while at the same thing heightening that of far away text. Why is that? See for example http://enwiki-trust.cse.ucsc.edu/index.php?title=Collation&diff=prev&oldid=102784135 - trust:6 text is added between trust:8 text, causing the surrounding text to go down to trust:6 or even trust:5, but at the same time improving text elsewhere in the page from trust:8 to trust:9. Why would the author count as low-reputation for the direct environment, but high-reputation farther away? -- Andre Engels, [EMAIL PROTECTED] ICQ: 6260644 -- Skype: a_engels _______________________________________________ Wiki-research-l mailing list [email protected] http://lists.wikimedia.org/mailman/listinfo/wiki-research-l
