Ah, something we need to clear up here: there's a difference between
"simple editor/application" and "simple UI". There is no such thing as
a simple editor. It's just not possible to be both "simple" and
"working". The OSM data model is complex and sophisticated, and any
attempts at a 'simple' editor will simply mess up other peoples work.
Especially when you start touching relations, which seeing as
relations themselves involve nodes and ways that's pretty much any
editor. I say this as someone who wrote the "split way but preserve
the order of route relations" code in P2.
But even the simple "rename a pub" editor is more complex than most
people realise. Naive implementations of a point-of-interest editor
break down as soon as they realise that all POIs can also be
represented by a closed way, and that these ways - both closed and
unclosed - can be part of multipolygons. It's complicated. POI != node
and Road != way.
However, we can certainly do much, much better at making simple
user-interfaces for these complex editors. In some cases we can hide
the complexity - like making pub-as-area have an icon and be just as
easily re-nameable as pub-as-point. But we should also split out the
ideas of "simple user-interface" from "hardly any features" interface.
An improvement I'd suggest straight away is to make road
classifications a drop-down. But if we want to have editors with
simple user interfaces (and I reckon we want that quite a lot) we need
to realise that they will be built on top of complex, sophisticated

Oh dear god, the wiki. How exactly something that is widely used and
supported can be called "rejected" is beyond me. Never mind that it's
apparently been "rejected" by a self-appointed group in favour of
something that hasn't even been "approved"!
