To each his own but if you aren't reading Celticsblog anymore, it's your loss. Celticsblog, as long as I've been a part of it has never been about the Celtics solely. It is a community where fans of the Boston Celtics can gather and talk about their favorite basetball team but also a wide variety of other subjects including the rest of the NBA, the Red Sox and MLB, the Patriots and the NFL, international soccer, and recently, the Boston Bruins and the NHL and current events, politics, relationships and even more.
It truly is an all inclusive community blog that just so happens to look at the world through green colored glasses. It's too bad that you find the diversity here unappealing but I am sure that there are others out there that you will find more to your specific tastes. I will say, however, good luck trying to find as high a quality site as this is dedicated just to the Celtics and nothing else.
And lastly, I think you're crazy not to enjoy the Daily Babble. Steve Weinman might be the finest blogging author around. He brings an objective perspective(when not talking about the Celtics), knowledge, and humor on a large span of subjects that keep the blog fresh and original. And Jeff is just fantastic. He seems to have his finger on the pulse of this team all the time and is as credible in his reporting of the team as any of the local beat writers for the major newspapers and more credible than almost all the national guys who think they know this team.
