circles / hashtags

[guaka]

Biggest circle is https://www.trustroots.org/circles/hitchhikers and we have #15 now

With filters #13 we can embed #18 this data on circle pages

Makes sense to encourage use of shorter tags i.e. #hitch - makes it easier to filter

future:

• encourage trustroots users to use hashtags in their profile descriptions, and link these to the map
