Sure. It's ok for lakes, woods, built-up areas, that sort of thing.  
I'm just looking at somewhere near Rhayader and it's pretty useful.

So would I, if I too lived somewhere with more people than sheep. The  
problem with that is when (say) you want to edit a lake somewhere in  
mid-Wales, you navigate to it using View as per usual, then click  
"Edit", and that zooms in to somewhere with absolutely no data. At  
which point you send a message to talk@ saying "where has the data  
gone I blame Potlatch pls to revert the changeset omgwtfbbq" - I'm not  
joking - and we all get a headache.

 From a usability point of view the View and Edit tabs should be  
equivalent - i.e. wherever you're viewing, clicking 'Edit' preserves  
the bbox.

We currently have a JS alert at z1-z10 saying "zoom in to edit map",  
and we italicise the tab to show that it's not clickable. (It should  
really be z1-z12, I'm not sure why it isn't.)

This is good. If it were context-sensitive depending on the amount of  
data in the area, it would be wonderful.
