Check out this site- I think they're on to something- kinda the "yelp of IT"-- either way, I like this post about Orion: Roundup of Latest Reviews: Solarwinds Orion (Network Monitoring Tools) | Station Master's blog
And I found these competitive posts... Network Monitoring Tools Companies | IT Central Station
I would love to see more Solarwinds posts... help me get the word out!
