basic recommendation system

We have one more poster session to go so it could still be useful

I think poster presenters still do not quite get the fact that there would be little to no attendance if everyone just stayed by their own poster. I think it would be useful to recommend them some to go visit while they are at theirs waiting for visitors. Thus particularly relates to #127 - if there was some listing of posters related to the current one visited. Finding recommendations could be done very crudely e.g. through % overlap between keywords which we already have for each poster in abstract field for each poster in abstacts.json, and placing e.g. 5 top hits within posters.json for each poster. But I would not be able to provide UI for that ;) @soichih - what do you think?

note: potentially better metric for a presenter could be the overlap with keywords from all his/her posters

I think that will be lovely! The presenter themselves can also curate such list themselves, right? They should probably be aware of other posters that they recommend checking out.

We could simply open up the etherpad when user clicks on the poster, and have the button to jump to video or open pdf. We can treat etherpad as a form of open-to-all white board. We should be able to do this pretty quickly.

For more proper recommendation system, I think we could ask for other volunteer to analyze the abstracts.json and come up a list of poster numbers to show for each poster? We can then later interegrate this information to the etherpad.
