[HOT] Getting organised

John,

I agree that HOT is evolving. I've been doing a lot of work personally to
clean up the Tasking Manager. Most of the discussion has been happening on
the Tasking Manager and Activation lists so it hasn't made its way to the
main HOT list. I reached out to the appropriate TM user and after checking
with them archived and deprioritized a lot of projects that had not
received any love recently. Blake also brought up the work and we had a
good conversation in the (Projects on the HOT OSM Tasking Manager -
lots of them)
thread.

I agree that we need to do a better job of managing and promoting our
projects. I don't agree with your proposal for doing it however. I
appreciate your proposal to reserve a couple of spots for MSF and Red Cross
but I think that ultimately it wouldn't have the effect you are hoping for.

MSF and Red Cross are driving tons of new users to HOT and OSM through the
Missing Maps projects. Having our projects on the front page isn't
mandatory to help complete our projects for us because our mappers are
mostly coming from mapathons or are searching for Missing Maps tasks. We
make a huge effort to finish all of our tasks, even for the Red Cross
spending lots of staff time to ensure they are completed. Lastly, I ensure
you we don't needlessly create tasks where we won't be doing field work.

I love the idea of a community spotlight somehow. Someway that we could
focus our collective attention to a not as well resourced project.

Basically all of this is to say that ensuring that when you create a
project in the Tasking Manager *you* are taking responsibility to ensure
that it is completed. In the past project creators have not effectively
managed resources and thus many left over forgotten half finished projects.

I'm happy to keep this conversation going as I'm very keen to get the TM
working the best way possible for the entire community.
