Maybe because they're unprofitable? Maybe because what's the point of pinning random items on a virtual pin board? Maybe because what's the need for $500M in capital for a website? Maybe because what good does Pinterest do for anyone or anything aside from waste time?

In Twitter's defense, while they might not "need" 100 engineers to rewrite their code, they are certainly infinitely more than just a glorified status feed.

Twitter has allowed millions of people across the globe to share insight into what is happening in their back yard. While for us Americans, this might include the dog taking a shit on a Macbook, in the Middle East it's far different. Twitter and FB have been responsible for a lot of insight and uprisings, especially during the Arab Spring.

Additionally, Twitter is an innovation in communications. Just like Skype is, but perhaps less so or just differently. Marc Andreessen said it perfectly: "Twitter is instant global public messaging - for free." That has some value vs. pinning my dress on a pin board.

Point is - SnapChat is worthless, Pinterest is less worthless but still has little value. Sure, advertisers and brands flock to the net since their old-school TV/print models are being replaced by technology - but very few "apps" are companies/businesses. And young users, particularly teens are very prone to jump ship like fleas off a dog when the "latest and greatest" comes about. Do you see SnapChat existing in 10 years? I don't think so. Pinterest? There will be something newer. FB? Twitter? Dropbox? Yeap, they'll still be around. And probably doing better than ever.
