"If you don't know where you're going, any road will get you there" is the journey of online self-study. There are lots of good paid and "free" online tutorials one might bump into whilst googling "banjo tutorials" and here's a "thank you" to the ones I've bumped into along the way.
http://artistworks.com/tony-trischka - A unique experience to get lessons with the same guy who once taught Mr. Fleck. A membership grants users access to video and audio interviews with some of the most influential banjo players of the 20+'st century.
http://www.banjobenclark.com - Banjo Ben Clark is a younger fella' who is clearly thinkin' of the best way to bring teaching and online self-study together in the most accessible possible way. His tabs are great, his videos are great. He does banjo, mandolin, guitar, and more (I just follow the banjo). He's serious about music, knows his stuff and still maintains the occasionally spark of goofiness, which always helps.
https://banjoteacher.com - This post would not be complete without a shout-out to the folks at BanjoTeacher.com (founded by Ross Nickerson) who I got my first banjo from. It was a great first introduction to the banjo. I bought a beginner package from this site. A Gold Tone Banjo set up nice, some DVDs, and maybe more (it's been a long time) were all delivered in A+ time.
