Almost two years ago I started writing my short posts on a similar premise on my blog https://arcticloon.fi. In fact, as of today, I'm four days short of writing every day for two whole years.
And all this time I have been writing alone, mostly for myself. I do have a few loyal followers and I see some random readers every now and then.
I think a community of other writers would be a great next step for me, so maybe I'll join in. But I'm not sure if I'd like to switch my writing and publishing platform just yet. Hope it's ok for me to keep writing on my own site and copy the texts over. Who knows, maybe in time I'll switch over. Or even better start writing on both places every day, doubling my output.
