Bitdeli co-founder here. We have missed GitHub's traffic graphs ever since they were removed and we know we're not alone[1]. That's why we decided to offer a free Bitdeli account to anyone who wants to find out who is viewing their repos.

The free account also works as a "sandbox tier" since you can try out all our features for custom analytics with familiar data from your repos.

Thanks to everyone who suggested this earlier[2]!
