American Idol judge Simon Cowell admits he doesn’t get the fascination people have with the online blogging site Twitter, which is growing in popularity. “It’s like phoning someone randomly, whose number you don’t have, and talking to them. ‘Hi, it’s Simon, I went out with my family this weekend’,” he told Extra. American Idol host (and pal, despite their bantering on the show — they were photographed jet skiing together in the Caribbean recently) Ryan Seacrest is a huge fan of Twitter, posting several “tweets” per day. When Cowell was read one of Seacrest’s Twitter messages, which said “spent weekend with my fam,” he replied: “What’s sad is that he’s having to use the Twitter language like he’s 17. ‘My fam’ – how difficult is it to add on an ‘ily’?” Simon obviously doesn’t realize that “tweets” are constricted to a number of letters — messages have to be fairly short, so abbreviations are common. Wonder if he read Seacrest’s reply to another Twitter member that said: “simon and paula were all over each other all night..plenty that wasn’t caught on camera!” Oo-la-la! ~Follow me on Twitter at movie_alex.
