I only tend to use it on my phone, so have seen no change, but my partner insists it's rubbish, stating she 'no longer enjoys using it!' Any re-design that makes someone say that has got to be a bad thing.
Its a bit annoying that the logout link is now hidden under a drop down menu. And it took me a while to figure out where my bottom menu bar went (obvious I know!). I don't know why they don't just leave it alone!
I have been a member for MyFace for ages and whenever they change the design it spawns several thousand groups dedicated to ripping apart their hard work but the fact of the matter is that the website has never worked properly imo - they are so close to nailing it as far as a user friendly interface is concerned.
There will always be people who don't like change, for me this new design is refreshing and makes a lot of sense.
They still need to fix their chat function though...and why on earth did they leave it where it is at the bottom of the page?
Still loads of room down the left hand side for open conversations and such.
