If you're at all interested in the development / progress of #writeas and #WriteFreely, I'd highly recommend following @writeas_dev.
Whereas I try to keep this account low-volume and limited to the important stuff, the dev account often contains what we're working on at any given moment, as well as new issues, small fixes, and our future plans.
Even if you're not a developer but instead run a WriteFreely instance — or just publish on one — there's relevant information for you there.
