Extra: Twitter, Identi.ca and July 4

First of all, if you're American, and you're reading this - I have to ask why? The web is like a ghost town today. There isn't much going on via Twitter. FriendFeed is unusually slow, and about six or so of our two trillion readers showed up to leave a comment today. It's July 4! Independence Day! Go out and have a brew and a hot dog! For all our non-American friends and readers, and the six US readers who have nothing else better to do, Sean P. Aune and I have recorded a special episode of Mashable Conversations today. We scoured the web and couldn't find a guest to come in today, so we reverted to a topic that had particularly irked us from the week past - the bizzarre assumption by some in the blogosphere that Identi.ca is the natural successor to Twitter. I won't steal the show's thunder, but Sean and I puzzle over this idea and try to figure out exactly why this is being said. It's a short episode, so go ahead and watch before you throw on your swimwear and jump in the pool this afternoon.
