As a creative writer in my free time, I sometime suffer from a lack of feedback. To get some impressions on what I've written, I either have to ask my girlfriend (who acts as a sort of beta-reader) or some friend. 

Now, my girlfriend doesn't seem to mind, but getting feedbacks from my friends is kind of difficult. I usually get no answer back - meaning that either my writings aren't interesting enough to be read, or they have better things to do. Either way, it has little sense to me to bother them further with this topic. If they don't read willingly, they won't give me honest feedback either, and I'll get "yea it was nice" answers at best.

So I was thinking: **is it a good idea to open a blog and publish stories there, or is it a waste of time?**

I've seen it done a couple of times, mostly by a local author in my country (she managed to publish on Amazon some of the stories who passed through the blog, also). 
She has a nice community of readers around her blog. 

I'd like to build something similar, but I understand it may be a waste of time - worse, free time I could have used to write instead. My other main worrying is that I'm after some cheap, ego-fulfilling way to pass the time, instead of doing something useful.

Note that I'm not searching for *beta readers* specifically, I'd just like to share my work with someone else. Writing makes less sense if my stuff mostly lays in a pc folder.

What's your take on the matter?
