Yep. It's a work-in-progress; if you know the local paths, go in and add them to the map!

But it's worth noting that partial coverage of rural footpaths is a lot more than TomTom ever has. ;)

Essentially OSM works on the principle of "with enough eyeballs, all bugs are shallow". There are cases of vandalism in OSM, but they don't last very long; the community usually picks them up rapidly and reverts them.

We have one advantage over Wikipedia in that it's easier for us to determine what's right. On Wikipedia, if one contributor says "John Doe's contribution to scholarship was important" and another says "no it wasn't", you get an edit war. On OSM, if one mapper says "this road is called Market Street" and another says "this road is called Market Road", we just go and look at the street sign. The rule is "what's on the ground". (The one place where this breaks down is disputed territorial borders, such as Northern Cyprus and Kashmir, but there are procedures in place for that.)

I'm always bemused why Apple doesn't bake closer iPhone/iPad integration into the Finder itself - the "root UI" of OS X, if you will. Shouldn't syncing between your Mac and your iPhone be a core service these days? And no, it doesn't solve the Windows problem - except if you're Apple. "See, if you have a PC you have to use this external app. But if you switch to a Mac, look how easy syncing is..." But then I'm an old grouch who thinks that Apple's once fabled UI consistency has been slowly getting messier from System 7.5 onwards.

...with Cowboy Neal as the final option.

First, ask on the OpenStreetMap mailing lists. There's lots of us who've done this kind of stuff before, and we'd be really pleased to help. I collected, scanned and rectified the Ordnance Survey's New Popular Edition - a complete set of England and Wales maps from the '50s, now out of copyright. It's all available in OpenStreetMap as a background layer and loads of people use it for adding rural roads, rivers, placenamese etc. Others are scanning other old Ordnance Survey series right now. Seriously, we love this kind of stuff. (#osm on OFTC can help too.)

Secondly, GDAL is definitely your friend. It's the most amazing set of command-line tools for rectifying and reprojecting data. gdalwarp and gdal_translate are probably the two you'll use most.

But there's not a lot point exporting the data if you don't have the rights to use it.
That's what the top-ranked Data Liberation suggestion is talking about - great that we can get the data out; but now allow us to use it elsewhere without fear of being sued for breach of copyrighted.

Try maps.cloudmade.com - there are numerous others. The point of OpenStreetMap is to make the data free so anyone can build a routing site, custom map or whatever - and not so much, in itself, to be an all-singing all-dancing alternative to Google Maps.

It also uses street data from OpenStreetMap. And, you know, this being Slashdot and all, you'd have thought the "open" stuff might be mildly interesting... maybe a bit more so than "New Site Uses The Same Maps API Seven Million Sites Have Used Before". Still, meh.

The author of TFA is renowned as one of the least clueful Apple apologists there is, even amongst plain ordinary OS X fanbois. He's also a regular sock-puppeteer, although not a very convincing one.

John C Welch rightly reams him out over this latest burst of idiocy. Worth reading for the headline ("Douchebags fondly eviscerated") and such prize comments as "You'd have to be smoking hobo crack (as in 'ass' not 'rock') to say that without snickering".
