I agree with most of what he wrote except on two points. Some of us are just lurkers by nature (online and in real space). For my entire internet lifespan, I've lurked - on Prodigy, AOL, BBS, USENET and now LJ.

I do make an effort try to post more often and comment more.

I've seen the Drama that can be caused by making public posts. Not for me, thank you. Some people (like theferrett) manage blogging in the limelight just fine. Others, not so much. I guess it comes down to where your sharing boundaries are.
