Well, specialization is good, but not as a newbie over here.
You should have to try as much as possible to touch every area and angle of the forum,
Try as much as possible to engage in every discussion you deem fit to talk about and always try to make yourself know now because time will come that you'll get busy and wouldn't have the time to work on your reputation.
You know, being here for 4 years, I'm still discovering places where I've never been before. And, surprisingly, there are a lot of them. For example, how can a person write about gambling if he is far from casinos and sports? In the same way, in the developers or miners sections, people write who have at least some idea about these topics.
It is silly to offer to have time to hang out in all sections since, by grabbing inches from each section, you may not grasp the very essence, simply from lack of time. Each person will always have their likes and interests, and I hope that the OP will be able to easily navigate where he is most drawn.
