I was on peakd once but have never been able to get back on there since. I don't know exactly what they did. I voiced an opinion that was counter to the subject matter. I brought it up to someone and they said you have to have an account so I tried to sign up and it kept coming up my username didn't exist or something like that.
Just like with these tags, you use them the first time and they'll usually give you a healthy upvote but that's the last upvote you ever get, must be you only get one upvote in a lifetime. lol. The only one that was different was Three Speak, they gave me quite a few upvotes here and there.
Peakd is great, as far as I know.
I don't know what is missing to know what isn't there.
I used to get votes years ago, but they have tightened up their circles.
When the top 20 accounts control 50% of the inflation, there is much less left for the rest of us.
I'm betting that there are plenty of sockpuppets draining the pool for what they are worth.
Control freaks gotta control.
