It always seems that way. I feel exactly as you do. Eventually I figured it out.
God gave everyone different gifts. Then He told us to "fill the earth", so we are all standing in a different place. The more interests that you try to match with a person you find, the farther you have to look to find them.
Go to the member search screen, and use advanced search, and see just how many of CC's over 50,000 members have posted more than 1000 times (123 as of this moment), or even a hundred times (667). Internet looks so big, yet the number of people actually connecting around Chrisitanity is quite a bit smaller than you might suspect. I grew up in a rather large city (Chicago) and I was in churches of over 1000 people. I doubt in my 22 years I lived there, I spoke to 600 people a hundred times each, or to 123 people a thousand times each, and that includes all my 20 or so K-12 school teachers, bosses at jobs, friends, classmates, and my parents and brother. Internet encourages us to expect more from social contact, than we are actually used to having, probably even capable of handling, and certainly more contact than anyone had in the days before internet was invented.
What's worse, is that every time someone concludes that these higher expections not being fulfilled is "wrong" somehow, they run the risk of withdrawing from society. Then they become one less person to be part of the group we all wish to contact, and we all get a little more isolated. I know for a fact (because I think in numbers like this), I have never, even in all my years of even full time ministry, had as much meaningful Christian interaction, by any measure or count I care to make, as I have had in the past 8 months of being in CC, only excepting the nearly 24/7 Godly contact with my wife for the time she was alive.
CC is far better than just about any other option, except the intimacy of marriage. You just have to accept the reality that you will always feel like you want more.
