Yes, agreeing to take part in a charity event is definitely a good thing, and I'm sure Georgia will do very well in that context. But there's a world of difference between a one-off charity event and becoming a judge on Strictly itself, and I agree that Alesha wasn't ideal. Although she did grow into the role, I feel she's much more suited to the BGT judging panel.
Obviously, people from the latin/ballroom world would be the best judges, but I'd even rather Bonnie Langford than another former contestant as a Strictly judge. (Actually, now that I think of it, that would be better than having another current Eastenders star as a contestant. As a judge, she'd only need to dedicate her Saturday to Strictly, and make the occasional appearance on ITT, and she wouldn't have to find time for daily training in the middle of a big and exhausting storyline.)
