I haven't used Yousician before, but it does look like cool.
If you care, I can give you a little advice though (been playing guitar for about 20 years.....and still learning). Aside from learning the basics (chords and scales, strumming, picking, etc.) and building up some stamina in your fingers, one of the most important things (in my opinion) is the amount of time you spend behind the guitar. Make your practice time count. It's really easy to grab a guitar and just mess around for 10-15 minutes, but those aren't the sessions that get you advancing/progressing. Try and have some kind of structure, and take yourself out of your comfort zone. For example, I will sit down and do a warm-up for 20-30 minutes (picking exercises, scales, chord progressions, or whatever else I may feel like). After that I will play through some songs. And get in the habit of finishing what you start, whether it be exercises or songs. Learn a song, and when you play it, go all the way through even if you make mistakes. It makes it hard to play with other musicians if you condition yourself to stop after every bad note. Just keep on pushing through. I'm rambling now....
Check this out:
Blues Guitar Institute - Acoustic Blues. Simplified.
This guy is a good instructor, and all of his lessons are in video format on the website and on his youtube channel. There are tons of good lessons on here, and if you could dedicate a lesson or two each week you'll be playing the blues in no time. You can pay for a membership if you want and that gets you all of the TABS in pdf format, but his videos are pretty good so it isn't necessary. A while back I had a membership here so I have all of the pdf TABS saved. If you are interested in this site, send me a PM and I can get you the TABS (i.e. don't pay for a membership).
