Four out of every 10 entries on the Twitter micro-blogging service are pointless drivel, according to research.
While many will be unsurprised by this particular finding in Pear Analytics' report, what might come as a shock is that nearly the same percentage of tweets actually form part of a coherent conversation.
"Many people still perceive Twitter as just mindless babble of people telling you what they are doing minute-by-minute; as if you care they are eating a sandwich at the moment," said Ryan Kelly of Pear Analytics.
Monday mornings at 1130 is the best time to get retweeted - when another member posts the same message as you to spread it to a wider audience - and news-related tweets are most frequent at 1400 on Tuesdays.
Tweets with "pass-along value" - those that are deemed worthy of retweeting - made up only 8.7 per cent of the total, while tweets categorised as spam made up 3.75 per cent.
The study itself has become a hot subject on Twitter, with 'Tweets Are Pointless' currently among the trending topics on the site.
