Currently, SE allows paying accounts to replace a 130x260 rectangle (I think?) with their own logo.
Non-paying accounts get... nothing.
May I suggest a compromise which I think will benefit non-paying SE accountt holders & SE as well.
In the case of non-paying accounts, that rectangle could be split into two parts-- each which a 130 pixel square, and one would be the SE logo, the other would be the users logo.
I don't see a down side-- SE continues to ad itself, now the user can ad himself, which incentivizes him to use SE... And the work needed to be done by whatever website programmer would surely be as trivial as it could be.
Thanks, plz let me know if you implement this notion,
