Thank you for writing this. I am here for exactly the same reasons. To write about life to share your thoughts or your little adventures, to vote on posts that have real content, to connect with people on the other side of the world, to learn how they live and the difficulties they encounter, etc. etc.
It's great to be part of this community and although it's very nice if people actually read your posts, and write a comment, its primarily the joy of writing itself, a kind of diary for the future. That is why I am here!!
