Twitter Saw 600K Signups Yesterday, It Took More Than 16 Months To Reach Its First 600K

Twitter is tweeting out milestones for its 5th birthday; So far we’ve got that there were 224 Tweets sent on July 15, 2006 (its launch day) and that now users send that many Tweets in less than a tenth of a second.

Twitter also saw more than 600,000 sign ups yesterday — for comparison it took the company more than 16 months to reach the first 600,000 Twitter accounts.

While I’m refreshing my screen to see if there’s any more, here’s a blast from the past: Mike’s post on Twitter’s launch: “Odeo released Twitter.”

Update: And Twitter has released its own “items delivered” number, 350 billion tweets a day. Google, which just revealed a billion items delivered daily on Google+, must be cowed. Facebook by comparison, is at 4 billion public items shared but of course it all depends on what your definition of share or a delivery is (Facebook’s for example includes all public status updates, photos, etc that users are sharing. Twitter and Google are counting how many times an update must be served to cover everyone’s follower streams).!/twitter/status/91891232489480192!/twitter/status/91889650175713280!/twitter/status/91889650175713280!/TwitterEng/status/91892509306920960
