Yes you are very right, we are but Humans.

I have been in so many channels where you try to communicate and you get ignored maybe they think all users in a channel are newbies.

I have been on particular channel where my salutations was ignored for days non stop and i had to eat a humble pie and left. To me such channels are many and i find them irritating, my only suggestion is to clamour on user interactions more often if networking is really the key...Like @stellabelle adviced to start a group, but why start a group where people don't interact but only want more upvotes?

So i'll rather stick with PAL and some others where even the whales acknowledges my interactions than start a new one.
