Documentary Ideas

I have so far come up with 2 ideas for my documentary project. These are:

1. What irritates about the place you live? What could be done to improve it?
2. Change in Technology?

1. For example, I live in Cambridge, United Kingdom. There are a numerous amount of people who complain about living here. It would really interesting to find out more about the reasons why they do not like living in Cambridge and their views on what could be done to make Cambridge more appealing.

2. How tecnology has changed in recent years different types, convergence etc.
