LOL @ fighting about clouds. Hahahaha! No, the blogs were personal blogs. Now they only have the admin guys' blogs. You could post comments though on other members' blogs. They were pretty well-moderated so didn't allow a lot of bickering. Mine was about space weather -- aurora, meteor showers, space exploration, eclipses, astrophotography, etc. The photography thing was excellent. You could upload your own photos (had to be at least sort of weather-related, of course), and a group of admin ppl could choose to appoint one of your photos with the coveted "Approvers Choice" which put your photo up at the top when users visited WU.
But alas, all that is gone now. I was a member since 2001. Still have a number of cyber friends from the old site... we've migrated to FB, Instagram, and Twitter. I've even met a couple of ppl from there IRL!
