<i>In my opinion, all it takes now, is the creation of a small number of killer-apps on clones platform to cement the fate of Twitter.</i><p>People have been saying this about Twitter since it only had ten users. It was a bit more believable back when Twitter was all-Fail Whale, all the time.<p>Now it just looks like a joke. If you want to predict that Twitter will suffer from competition you must at least <i>name</i> the competition. I see that you kept your list of names safely behind a link. That was a good choice, because the list makes the joke even funnier. (<i>Skittr</i>? <i>Yonkly</i>? <i>Kwippy</i>? Were these auto-generated? Has anyone actually heard of any of these things? My favorite example is the mighty "Dukudu" empire: "auctioned off on eBay, acquired by allesklar.de for EUR 43,208". Ooh, a whole EUR 43k! I'm sure the guys on Sand Hill Road are trembling with fear.)<p>(Not that I begrudge these projects their marketshare. I'm sure they're being run by fine people. I have a funny idea for a microblogging site myself, and I might even launch it with a hilariously silly name. But I'll try to resist the urge to have delusions of grandeur.)<p>Incidentally, how can a business simultaneously have no business model <i>and</i> be mortally threatened by a patent infringement suit? If the patent troll wins and is awarded a 12% royalty, do they have to accept 12% of the losses? ;)
