Your right. At the moment, I am still lost, clueless how to get started and being more involve with the community. I believe there is more to it than just writing post, using the right tag and "hoping" for the random upvote.

Also, the current tag system is lacking in functionality as we can't save it or put it in the feed to browse for content that has our preferences to it. Or am I missing out something such as following a group such as the kind of facebook group thingy, so that content that are most relevant only appears?

As of my current experience the current tag = group(community)?

Just felt that, you are able to answer to my question and help guide through this. Cheers.
