[Talk-us] Maximum number of tasks on US tasker

[Martijn van Exel]

I'd like to learn more about that massive mess and how we can prevent
that in the future, Paul.To my mind, most TIGER clean up consists of atomic tasks, which is where
MapRoulette would typically come in really handy. (Remember the 70,000
connectivity errors we fixed in 2013/4, and the 100,000+ missing
railroad crossings which were also attributable to TIGER .) But perhaps
you have something different in mind. I'd like to think MapRoulette can
help, also because not everybody prefers the same style of working on
large projects.--
