There are a lot of cities trending towards making information like this more easily accessible. It'd be even better if there was some form of standardization between cities though.
ISO standards were just agreed on, in fact.

Case in point, my hackathon group helped hook them up with our city and our entire event was based on hacking this data. But the city basically did some straight sql table dumps without normalizing everything (so you would have to query multiple sets of data to make sense of anything) AND the city redacted a bunch of data, like I dunno, the frikkin relational IDs of some of the really juicy data, making it effectively worthless.
Socrata is in such a land grab that it appears that they're not too interested in whether or not the data is any good. They just take what the gov'ts give them and dump it in.
Maybe they've fixed that a bit since, but it was highly annoying at the time (last fall I think).
Quite a lot. Enough in fact that they have a set of private bus routes to various districts of the city. Though people don't protest them to nearly the same volume as they do in SF.

It's a long way off the likes of Seattle and data.gov.uk, but it's a huge step forwards in terms on openness. It's great seeing cities start to make this data available and people coming up with interesting ideas to use the data.
This is an area for which it seems like there are very few competing products, and from my experiences with it in the past it's a very easy and intuitive product for non-technical users. IIRC it can take things like Excel spreadsheets and handle all the import and arranging for them.
The ease of use was certainly a big sell for the agencies in Hawaii. They're already typically understaffed and dealing with lots of red tape, the last thing they want is to have to fight with a system to get data out. As with anything, if you make it hard for people, most won't bother.
If HN people are looking for a market to compete in, this one might be interesting :)

CKAN in particular is used by a lot of National Governments ( http://ckan.org/instances/ ) , is Open Source, has a reasonably large developer community. It also isn't quite as expensive as some of the closed source commercial offerings.
There are a few more but in various stages of completion/usefulness.
