Did you know that RSS is a disease? If you've ever had RSS overload-itis, you know what I'm talking about.
Blogging is a bit like (as I've mentioned before) ostrich farming...and ostrich farmers like to promote the eating of more ostrich...leading us to often say "you should read this new blog," "this blog is a must read," "blog, w00t w00t blog," etc.
If you followed all of the "must read" advice you received, soon you'd be overwhelmed with hundreds and hundreds of blogs in your aggregator, reminding me of my grandmother and owls (she collected owls...plates, pictures, figurines, etc...she must have ened up with thousands and thousands). While it makes for an interesting conversation piece, "who" has time for it?
One of the first visible symptoms of RSS overload-itis is an urge to delete blog posts en masse just to clear them. Been there, done that.
However, I've found a solution Dean Wormer would be proud of. Probation, double secret probation.
Most aggregators allow you to create "groups" for your blogs. I have groups for "blawgs," "bored," "technology," etc. (see a picture below). The most important group of all is called "Probation." Into the Probation group goes every new blog I add to my aggregator. EVERY one. Consider it a quarantine tank for your RSS aquarium. Once a month, go through your Probation group and cull the herd, promoting some to the big leagues, while giving others the boot.
Shoot...when a blog starts getting lame, I demote it to the Probation group, a first step on the way out of my aggregator.
So...do yourself a favor and put new blogs on probation.
