Gotten started with just suttas? I'd say that I did. Thanissaro's translations on you-know-where were the first real Buddhist literature I had ever read, besides some insubstantial and vague summaries on the different schools of Buddhism and what they're all about. But it's when I started reading suttas that things really began to make sense, so I'd say that's how I initially stuck my foot through the door. I don't restrict myself entirely to that body of literature, but it put gas in the tank well enough, so to say.
Then Thanissaro is in effect one of your teachers. Not only did he translate the texts on that site, but also the very fact that he chooses to put some texts there, but not others, is also an important thing to keep in mind. In other words, even just straight out reading on AtI is coming through a kind of filter of sorts.
I don't mean, by this, to imply that this is a bad filter, or that one shouldn't do this. I just wish to point out that it is not some kind of "personal un-mediated interaction with the suttas" at all. We should at least acknowledge this part of the process.
