Hello. I'm Jany. My Tumblr is pronounced Thilly Tenny. Yes, the first word has the "th" and the second doesn't.
Here is where I tumblr and reblog random stuffs. If you wanna read more, here is where I write... when I so inclined.
Tumblr Growth
I was curious how fast Tumblr was growing as a business, so I decided to spend a few minutes looking into the data. It turns out each post on Tumblr is assigned a sequential ID number that you can use to estimate the total number of posts on the site. For example, my post earlier today was ID 48896513 and a post of mine from a week ago was ID 47971938. By subtracting those two numbers, you learn that all Tumblr users posted over 940k items in the last week. I repeated that exercise over all my posts for more than a year to arrive at the chart above, which shows total Tumblr posts per day.
The results are interesting, I think. You can see that growth has been fairly steady since the beginning of 2008. The trend is good, though not quite as dramatic as some highly viral businesses that I’ve had data access to in the past. I’m not sure what the cause is for the unusually high post rate between August and October 2007, but I imagine it has to do with the affiliate spam problem that Marco has mentioned on a few occasions. Not surprisingly, the number of posts per day falls significantly over the Holidays.
Ok, enough of that… back to work.
Wow this is quite impressive. I’d be curious to know the # of users, posts per and difference in indiv tumblrs vs. group tumblrs. I guess that would require some inside data though.
Thanks joelaz for putting this together. :)
