I've just taken a quick look at the last 8 skills you've learnt. You *should* be getting something from your Rock/Familiar which makes use of your new-found abilities.
Have you tried pressing 'F' and taking a look through your Quests section?
Your Rock/Familiar *should* be promping conversation in which they give you new quests. If they're not, log a bug and hopefully a member of the Staff team will get in contact with you.
If you've been cramming through skills offline (either the home page or the GlitchHQ app for iPhone), sometimes it takes the rock a bit to ping you in-game with your quests.
You can always click on the rock, or press 'F' to call it up and review your quests manually.
If you're looking for the popup, sometimes they get queued up when you have a lot. If your Familiar or Rock has a red number that means you have new quests awaiting your attention.
