I've added a new feature to FanConcert today: if an artist needs to be updated, you can tag it with Needs Updating. This tag will last for 60 days before it is automatically removed, unlike the other permanent tags like Favourites. I'm calling these tags transient tags because they disappear after a while.

Why remove the tag after 60 days? Bands have periods of activity and inactivity. When a band is on tour, they may be constantly adding new dates so they constantly need updating even after they announce their initial tour dates. Keeping the tag around for a short period covers that and you can re-tag the artist to reset the 60 day period over and over again if you need to. By automatically removing the tag after 60 days, the system is just reflecting the fact that the users don't need information about that band any more because the band is inactive.

These tags also give focus to bands that people want updated, purely from a popularity angle. If you're actively looking for bands to update to get more reputation points, I've made a list of the artists that are most tagged as requiring updates: 50 Top Artists to Update. But it doesn't stop at just adding the concert dates -- other people can score the dates that have already been entered, which is why I don't mind that the Needs Updating tags stay around for two months. It would be nice if people are constantly checking that the dates are correct while the band is still actively on tour.

Here's the best part though: If you're too busy to add concerts for an artist but know they should be there, you can just quickly tag the artist with Needs Updating and someone else will handle it. You can still contribute to FanConcert by alerting other people about bands that need updates without having to do any data entry yourself. I'm just looking out for my lazy contributors out there. ;)
