I have a blog on my own website, but I'm not sure how many people actually read it. Although I reckon quite a few of my friends read my posts now, as I've 'connected' my blog to my Facebook, Twitter and a Dutch equivalent of Facebook, making my posts appear on all three of them accounts.
It helps me to post on there, although I don't post all my thoughts there as some of my feelings and thoughts aren't really meant for my friends to be read. Those things, the more 'dark' things I usually just post on this site in the "Members Diaries" bit. Not sure how many people read that either, and to be honest I don't care that much, as it's mostly just for me to get things off my chest. (although, admittedly, it is nice to think that my words are heard by at least a few members).
One of my biggest wishes is that my words in my blog posts (especially on my website) sometimes inspire other people, or at least put a smile on their faces, or that they can relate.. Guess I just hope to be able to touch people in some way. And of course it's therapeutic to get things off my chest.
Hope that helps. =)
