Shops and offices are not really temporary, they change but over
relatively long periods of time. Bus routes are similar, they do not
change very often.
We really should not be tagging broken bollards as the restriction they
are there to enforce are still there, and they will be fixed quickly
(even if its initially by placing a cone over the broken bollard.

If we did that, we would have a much poorer map. There are not enough of
us to monitor everywhere with that frequency. If we only mapped places
we visit more than once a year, there would be huge holes in the map.

It is important that we get this right, this is where we are, or will
be, judged. The road in question is unclassified and in this case people
who do not know the are will just be taken a different way. But maybe a
user has seen it and gone back to a closed source satnav, we will never
know.
At present I suspect the number using OSM based satnav will make Linux
desktop usage seem a big success ( yes I am a linux user ), and I do not
want to buy another 'closed source' satnav.

A tree across a path is something that will again be removed within at
most a week or so, if it is causing an obstruction. Otherwise the path
may move around it, but it is too short term to map, and if the path is
public then it is the responsibility of the local highway authority to
keep the path clear. Time will vary, especially after a big storm, but
in general its temporary and a phone call is better than mapping.
Vegetation is seasonal, long grass will be gone by Autumn/Fall. If its
causing a real obstruction then report it. And carry some secateurs, so
you can trim it back a bit.

Or we may deter someone from walking a perfectly clear path.
