With the exponential growth of twitter in just a few months, there has been some talk that Twitter and Ruby on Rails may not be able to scale. There are some posts today that say that is not the case. Anyway, I am sure that the guys at Obvious and Twitter will FIND a way to make it scale. Every new user and page-view on their hockey-stick-like usage graphs is like cash in the bank. Ok, more like a loan or a promissary note maybe. The point is that they will find the technical solution and the cash to do it, whatever it takes. More users and popularity has got to be adding to their valuation by the month, week, day and even hour. The 64,000 dollar question remains however. Will they sell out our keep growing it into a revenue producing business?

Oh, and if you are interested in those posts, they are here and a more technically minded one here .
