Hi! I just turned 24. Being a native French speaker living in Montreal, I can't say that I grew up with Sesame Street (I didn't speak or understand English at the time!), but the characters soon won me over, and I loved the books/comics, too. In the late-1980s, I was also a big fan of Fraggle Rock...
Recently I've been going back to Sesame Street, reading about its history; my favourite Muppet has always been Grover, but I love others, too. I approach SS much like I approach mythology, legends, fairy tales, etc. -- as powerful (and often surreal) expressions of imagination, and as works that can appeal to young children and adults alike, with many layers of meaning.
Fantastic site and forums, by the way!
