Alan Patrick thinks not:
Is it a fair price – no, of course not, its a Bubblenomics business case. In any “normal” economy, paying $40m for a zero-revenue feature that uses your own platform to organise what are essentially SMS’s with pictures into columns, is completely daft. You can build that for a few hundred thousand and probably bribe a user base the size of Tweetdeck’s to comeover for far less – but it’s BubbleTime, and in BubbleTime its all about the urgent acquisition of eyeballs (remember them from Dotcom 1.0) Now!
It’s a harsh description of Tweetdeck, but a true one.
