In August 2011, we did a round-up of the 23 best inbound marketing blogs on the internet. But that was soooo two years ago, and it's high time we gave that list a refresh, don't you think?

I spend a lot of time reading these bad boys, and so do my colleagues here at HubSpot. But I'm always looking for new reading material! So read through this list -- keeping in mind these are not ranked in order of awesomeness, but in order of alphabeticalness -- and let me know if there are some other amazing blogs we should consider for next year's list! I hope this gives you some new reading material to enjoy with your morning coffee.
