Comics icon Stan Lee celebrated his 90th birthday Friday, inspiring a flood of congratulations on Twitter, where he posts as @TheRealStanLee. Fans, celebrities, colleagues and even a few superheroes sent their love to Marvel Comics' "Generalissimo," and Lee's trademark catchphrase, "Excelsior," got the hashtag treatment.

This was a busy year for Lee: The legendary co-creator of classic characters like the X-Men, Iron Man and the Hulk launched a YouTube channel, Stan Lee's World of Heroes, this summer. He also hosted his own comic convention, Comikaze, in September. This year also marked the 50th birthday of perhaps Lee's most famous creation: the friendly neighborhood Spider-Man.

Mashable talked with Stan "The Man" twice this year about his ongoing web projects: once at the launch of his YouTube channel, and again at New York Comic-Con. Check out the gallery above to see who else was talking about Lee on his big day.
