I mean I don't always follow them but yes! I use subscriptions pretty much only for WIPs, it just hasn't really worked for me with authors, so I won't see your stuff otherwise unless I stumble on it in a tag filter. And some people I may not even know you write fic at all. Plus it's a weblog, log what you're doing, be proud of it.

But also I just think in general it's better to actually say to the people who already want to read your stuff "Hey I wrote a thing, I hope you read it!" than to just toss it into the scrum and hope.
