Someone PLEASE turn off the Live Blogging hosepipe!

Once again, hundreds or maybe thousands of people, attending the SAME event at the SAME time are ‘live blogging’ the SAME content to (mostly) the SAME people.
So-called ‘live blogging’ was once a useful practice, where a small number of people attending an event, would send key messages via Twitter, to their targeted followers.
Live blogging Blog World Expo #bwe
However, today – when almost every attendee at these events is tweeting everything they hear, live blogging has become (at best) a nuisance for Twitter users. The deluge of duplicate messages coming from is week’s Blog World Expo #bwe is the latest example.
At one point yesterday, I saw the same Tweet on my screen 7 times in around 3 minutes. Yes, of course I unfollowed the culprits!
Live blogging from the gurus
There is something REALLY funny, about listening to the worlds leading ‘social media gurus,’ spraying the same hosepipe of identical information to their followers. After all, THESE GUYS are the self-appointed experts. Their inability to realise how pointless it is, to tweet the exact same ‘news’ as the guy sitting next to them is laughable.
Maybe they need to read their own books on how to use Twitter, (great value at just $9.99! with coupon code #bullshit.)
Live blogging does still have a place, as was very powerfully demonstrated at a number of recent, under-reported world events. But to sit in an air-conditioned exhibition venue, surrounded by thousands of people already tweeting every point made by every speaker is insane. If these people REALLY want to provide something of value, surely it would be better to write a blog post, based on THEIR unique understanding of what they discovered?
Am I being unfair here?
