<div>So 45 of 79 new contributors (57%) made errors with
P2, 16 of 33 (48%) with iD, 2 of 5 (40%) with JOSM, and
3 of 6 (50%) with other editors. While there's no doubt
a fair margin of error here, what I conclude from this
is while it's still much too easy for new contributors
to make mistakes with our current editors, there's some
indication that they make fewer errors (especially
serious ones) with iD than with P2.</div>

<div>If you have time, I would love to see more numbers in
the future or changeset examples that show what types of
errors are most common.</div>

No problem - at current rate of registration there'll be 50 or so
new mappers in that same area in a couple of weeks or so (the rate
will hopefully go up with press such as <a
href="https://news.ycombinator.com/item?id=6265150">https://news.ycombinator.com/item?id=6265150</a>
), so I'll have a look then.<br>
<br>
I'm a bit wary of posting "individual user errors" in a searchable
public forum (I wouldn't have wanted my "new user errors" preserved
for posterity in that way!) but will try recreate and summarise the
common ones below. Of course the iD versions used in the data above
and the summaries below won't be current so these issues may already
have been addressed.<br>
<br>
1) A POI added without a main tag<br>
<br>
<a href="http://api06.dev.openstreetmap.org/browse/node/4295739963">http://api06.dev.openstreetmap.org/browse/node/4295739963</a><br>
<br>
I suspect that people are adding a "point" to a map (in this case
for a shop), and are not seeing "shop" in the default list to the
left or understanding that they can search. In my experience the
search works really well, and once a "point" has been added by
mistake the "change feature" tooltip is pretty obvious too - so I've
no idea how to improve here!<br>
<br>
2) Thing X changed to thing Y<br>
<br>
<a href="http://api06.dev.openstreetmap.org/browse/way/4295035814">http://api06.dev.openstreetmap.org/browse/way/4295035814</a><br>
<br>
There have been a couple of examples of people clicking in an area
(in this example landuse=residential) and then changing it to match
the POI or area that they're trying to add, resulting in something
like this unfeasibly large place of worship.<br>
<br>
3) Deletions<br>
<br>
<a href="http://api06.dev.openstreetmap.org/browse/changeset/30174">http://api06.dev.openstreetmap.org/browse/changeset/30174</a><br>
<br>
I've no idea whether things are being deleted by clicking on the
rubbish bin icon or pressing the keyboard shortcut. According to
comments on #osm-gb there have been a couple of attempts to find out
what buttons people are clicking, but the answer is "I didn't mean
to do X - I've no idea how it happened".<br>
<br>
