The problem: The tooltip of a wiki article in the feed has no information whatsoever. Here is an example:

In its current form, this tooltip overlay has not more information than the text which triggers the tooltip. Our wiki is nested, so it would be really nice to see more than the title.

Proposal for a better tooltip:

<article title>
------------------------------
Wiki Page * <tags>
<full wiki path of article>
Last Author: <author>
Last Edited: <datetime>
