I started working with Django about 6 months ago and have loved it. I had been a long time anti-framework guy, but can't say I have had any huge complaints with Django so far.

I particularly have enjoyed the ORM, although you need to be careful not to get carried away with it. Its easy to create slow queries with it and don't assume it will always get indexes correct.

I have also enjoyed the community around Django. I enjoy being able to search a particular problem and find that someone already has created a Django app to solve it. In my PHP days (RIP) this was possible, but usually ended up being a lot more ugly.
