But for my main account, I'm quite happy to pay Github their not very many £s per month.
And this is just one of the many, many benefits. Soon you'll have 3M users, then 5M, then 10M... who knows how big it'll get.
Github made it easier to share code and created a community. Now more people share. Github standardized project formats (which dougws points out below). It's easier to figure out what's in a library.
This makes it easier for me to build complex apps. It saves my company gob loads of time & money. I fucking love Github and I fucking love people who use it to share high quality code that I don't have to recreate.
So much has changed just in the last few years :-)
But recently I've really begun to question Git for version control, two recent experiences are really making me reconsider with its complexity outweighs its perceived usefullness. Its quite possible that for at least one of the projects I am involved in we will move back to SVN for the next version build.
On average most accounts I've seen have far more than 1 and a half repositories.
Or those numbers could just be bollocks.
