I usually hit the solarwinds.com site once a week for some reason or another. Usually looking for product info, updates, patches or knowledge base articles. Oh and those pesky MIB files.
I think I joined thwack about 6 months after I inherited a Solarwinds install. I try to visit daily but there are periods where I am not on for weeks. I usually look for shared content from the community or insight into an issue we are having or something we are trying to accomplish.
