@Shantanu You're right. To get noticed, one needs to immerse oneself in a community, any community. This is what I feel. Everyone is a nobody when they start out. One can't expect people to come and read their blog if they are not reaching out to them in the first place. Commenting, social media engagement and then that hope of reciprocation is all a part of this "getting readership and attracting audience" game, at least till that stage when you build a name for yourself such that you no longer need any of these anymore.
True, it requires a lot of hard work, dedication, passion and commitment to reach the higher stages and so many bloggers burn out in this phase itself. As you said, it is important to keep working towards it, the path does not matter, so long as it does not hurt your conscience, it's good. What's good about it is that eventually, you have the complete freedom to build your community -- in the 'right way' because there is no dearth of incredible people out there who share your interests, are waiting to read you, support you and also help you out.
