The problem is that you don't know what you don't know. I see a lot of libraries, articles, technologies, etc that I wouldn't otherwise see, and wouldn't know to Google.
Not sure I explained that well, but I think you can get my meaning.
Twitter can be a distraction (and I let it be more than I should), but like anything else it can be managed.
Not aimed at you, but too many people are searching for that magic "something" that will help them be awesome. When you get to the top of a field and talk with your peers, you realise that everyone else has the same questions as you, and that the answers come slowly and loudly. It's hard to miss truly great things.
