It is tough at the start I had a bit of a period where I felt like I was talking to myself (and still sometimes feel like that) but I have managed to engage with some awesome steemians who leave engaging comments whcih seems to make it worth while for me.
I go through my following list often - some people are no longer active, some are no longer relevant to me, some resteem to much! Its about finding a balance and finding what works best for you :)
I love following and supporting lots of people but I hate not recognizing people on my list and not knowing anything about others. I will probably pick 2-3 people a day to reacquaint myself with.
