In case you missed it ... Hillsborough, Jools Holland, Elizabeth McGovern and the art of unfriending

We publish a lot of stories here on guardian.co.uk. On an average day, around 400 stories are launched by our editorial team and sometimes you might miss some of the best ones if you don't check the site regularly. So, for the last year, we've been running an experiment using data from Guardian Zeitgeist to find the long stories which our users are spending the most time reading - and then using the Guardian Open Platform to republish these stories on a site called thelonggoodread.com . We have even experimented with turning these stories into a newspaper . Two new stories are added to The Long Good Read each day which have recently been published and then enjoyed on guardian.co.uk - and you can visit the Long Good Read site , subscribe via RSS or follow @TheLongGoodRead on Twitter to receive these daily recommendations.
