Amid the flurry of photo and video-sharing start-ups, it is interesting to see Shutterfly file for a $73-million IPO. Remember Shutterfly - the online photo service company that popped up during the dot-com boom along with rivals such as Ofoto and Snapfish? Shutterfly's high-profile investors include Jim Clark (remember him?) and Tom Jermoluk. According to the company's S-1 filing with SEC, Shutterly had operating income of $4.4-million on revenue of $83.9-million last year. This compares with operating income of $3.9-million on revenue of $54.4-million in 2004. So, unlike all those Web 2.0 photo "newbies", Shutterfly is a real company with real revenue and profits. I wonder whether investors will snap up the IPO shares, which will be sold at $13 to $15.
