A very comprehensive database source of US-city neighborhoods digitized at
very high spatial resolution, as well as a source of global neighborhoods
digitized at equally high spatial resolution, may also be found at
www.datahunt.com, which brings together neighborhood researchers from a
number of countries. Datahunt.com positions itself as a "global
neighborhood research group" providing neighborhood maps for developing
non-commercial neighborhood applications (such as working with government
agencies, NGOs etc).

I've also come across these 2 commercial sources with US data, but don't
have any direct experience with them:

Curious to hear if anyone else does...

For multiple cities I don't know but San Francisco has some neighborhood

department are at

I think there is another one from SF realtors association but it is
different. I mention these because you mentioned SoMa. From what I
remember seeing of the Flickr neighborhood data it was fairly similar if
not as "clean." The neighborhood lines didn't always run along streets
the way the official dataset does. Other cities might have something
similar.

Flickr used geotagged photos to generate shapefiles that include
neighborhoods, and released the data into the public domain:
http://code.flickr.com/blog/2008/10/30/the-shape-of-alpha/
The data is quite valuable but definitely is not perfect - depending on
your needs, you may need to curate it.
As another option, Urban Mapping offers a fairly rich
neighborhood-oriented webservice API on a fee-per-query model. As such
you won't get the polygons from it; for that you'll need to a direct
licensing agreement (not sure what their pricing is on that but under low
to moderate query volume the API would be more cost efficient.) See
http://www.urbanmapping.com/products/urbanware/neighborhoods/
So you have the Zillow shapes, Flickr shapes, and Urban Mapping's API as
the main options as far as I'm aware, each with various pros/cons. I'd be
curious to hear more about your intended use case.
Anyone know if the OSM folks are thinking at all about neighborhoods?
