An idea that came to me the other night: maybe adding some way to closely integrate Read.as with WriteFreely, for anyone who wants to host an instance with more than just the writing experience.
Probably need to implement oauth so users can have one identity across e.g. writefreelyinstance.com and read.writefreelyinstance.com. Or maybe they just share data somehow; Read.as boosts get posted to WriteFreely blogs, etc. Could be really interesting combining them in new ways.
