I personally like to use Twitter. The number of characters is limited and you can't say much but you can use GIF's or other media. What I like about Twitter is that people will interact even if they don't know you. The game development/indie game development community there is pretty big and it is easy to find interesting content to see and give your opinion about it. I can give you a couple of people to follow if you are interested.

Regarding the right place as you say, it's really subjective to me. You can find a platform that you are comfortable in and you can develop your community there or interact with other developers. There is not one "good platform", if you fit well somewhere than it is a good platform for you but for some others it may not be so. 

Thanks for the reply! I am definitely interested in getting some more people to follow on Twitter. I am a heavy Twitter lurker :P But I hope to become more vocal with this whole experience.

You will get there over time 

I follow quite a bit of people on Twitter, here are some people I remember @sylvia_ritter@EC_DanielFloyd@punchesbears@talecrafter.

Maybe you want to check out my twitter following list or we can discuss wider via Twitter. If so here it is my Twitter @WimGames. I'd be glad.
