So far I have found Drupal 7 very easy to install, e.g. no messing about with renaming default.settings.php.
The last year has been an interesting time for Drupal, first drupal.org was redesigned and I can't mention this without putting the credit to Mark Boulton, Leisa Reichelt and everyone else behind it. New site so much easier to use and looks so much nicer. My two favourite features of the new site are the dashboard I get if I am logged in, which makes keeping up to date with my recent activity a lot easier. My second favourite feature is the fixed width, I don't know what it is but a website with a 100% fluid width just drives me mad (this may just be because I have a 22" monitor at work).
If you have worked with Drupal 7 you may of noticed that this site is now running on it. You might also notice that I haven't added much as I am still getting started with it but I will be updating the site as I go.
