Personally, Steem changed a lot for me, in particular through the SteemSTEM project. I arrived here as someone who never blogged about anything and I started to write. This somehow opened my eyes in the importance of doing outreach about what scientists work on. From there, things escalated quickly and I am now trying to bring my own stone to the whole science communication business, as one of the managers of SteemSTEM. I still don't know whether this will be a success, but I will do my best. Science communication is vital today and there is a good share for Steem in there. 

On the side, I have fun, I met a lot of people from all over the world and co-organized a small number of really cool meetup events. Steem includes also a social part. ^^

So in short, Steem indeed goes way beyond the blogging paradigm. Steem can be used for much more than that, and it is actually already used for much more than that. The final usage is also what we will decide it to be, and today is still the right moment to build projects on Steem.
