[Talk-GB] Implicit speed limits: What to tag in built-up areas?

[David Woolley]

Two or three years ago, we had problem of lots of bogus "wrong speed 
limit" notes being added by one particular app.  The general result ws 
that no-one took any notice of the notes from that app.  More recently, 
we have had problems from maps.me, although possibly not for speed limits.

I think it can be quite dangerous to give people apps that fix or note 
particular problems to people who don't know how to map using the more 
general tools.

I don't know about your tool, but it is essential that every user has an 
explicit personal account with OSM, and that they are set up to receive 
emails if people add changeset comments, or post messages to their OSM 
account.  maps.me has a high incidence of people who seem not to notice 
changeset comments.
