Hovercards shows little of interest for LiquidThreads and nothing for Flow talk pages.

It would be nice if the Popup showed

• some indication of activity such as a count of topics
• a text extract of the header of a Flow board if it's "interesting".
• the date of most recent activity (which is not the same as the page revision's timestamp).

Note the MobileFrontend alpha shows a count of open topics within its icon for a conventional wiki talk page; it does this by retrieving the 'page_top_level_section_count' page property. This was discussed on the design mailing list starting with http://lists.wikimedia.org/pipermail/design/2014-May/001825.html.

The implementation of this might end up in Flow and Extension:TextExtracts and maybe ContentHandler; I'm filing it here because it's where people notice the feature.
