Unclear what you intended to express via “following” — are you saying building community of followers is a route to finding a startup community open anonymous users? If not, what did you mean?
To me, posting comments with notes for yourself is basically spam, especially comment like “following” - which adds less value than just upvoting a comment; to follow comment, just click the timestamp to bookmark it and/or sign-in, upvote it, then look through your upvoted comments in your profile.
