I'm not sure why you gave us a screenshot, rather than just typing out the network, and how many users it has on the channel. Feels like it'd be a lot less work! :)

Number of people on channel is in no way a good indicator of activity. There are very active channels with 2-4 people and totally unactive channels with even hundreds of people.

Yeah the number of people LOGGED in is totally different then active. I am always "logged" in just so I get to keep the cache of the dialogues. If one channel has 100 people you might be there all alone.
