Some of those places voting Yes to AV are notable for the fact that they are exactly the type of places where AV would have made a difference:
Hampstead is a 3-way marginal with a majority of 42 (winner had 32.8% of votes cast).
Oxford West has a majority of 176 but in the general election the Greens did quite badly in Oxford, contrary to their position in the local council for a couple of decades. I suspect Green voters, as well as many others, voted tactically in the Oxford East and Oxford West at the general election.
Cambridge is very similar to Lewisham West - with two parties close together in second place.
Edinburgh has four party politics while Glasgow has one party politics (actually SNP are quite weak in Edinburgh but growing in strength in Glasgow).

I have a suspicion based on this that in Lewisham, where the vote was so close, Yes to AV may actually have won in Lewisham West, which is currently the more marginal of the three constituencies. Not that it really matters, the nation has spoken and democratic reform will just have to move forward in the House of Lords faster than in the Commons. Although the cheaper option would just be to scrap the second chamber entirely and remove all the scrutinity that takes place in the Lords.
