If someone still wants to do this, more power to them. I definitely think there is value in just writing for yourself and putting it out there.
But then again, the internet has changed so much even in the last few years. I used to blog but gave it up.
Journaling offers me a similar outlet, and I dont have to bother with web hosting on a website that reminds me every time I look that nobody else is reading my stuff. (At least for me.)
But I recognize this is just my experience. I know it isnt like this for everyone. If it still helps someone find meaning, I say go for it.
