You'd be surprised how good and feature rich plain ole top actually is. My guess is you rarely deviate from the default options. I made a video which shows how you can get top to show you some pretty interesting stuff.
I think social network spamming has become much more popular, I wonder if this also has had an effect as people leave traditional email spam (or don't worry about replacing it when governments shut them down).
I never really understood why pagination links expire. Most sites don't expire, you just have to deal with knowing that content that WAS on page 3 when you loaded page 2 might have changed.
Google+ is less a graveyard (see MySpace) and more like a new frontier full of pioneers but lacking the 'general public' that makes it feel built out like FB does.
If it helps, I'm a data point who's seen lots of Google+ activity among close and remote friends, embraced by many who were avid Facebook users (I wasn't). I can't compare it with others from my point of view since I joined other social networks late, but it seems to be doing quite well with people I know. The much feared group inertia was given a quick and solid kick by Google+ in my case.
Just thought I'd balance the comments about it being empty and inactive.
Our AgileTask (http://agiletask.me/ , shameless plug!) team just had a giant brainstorming session on how to try and get more traction.
We did the simple rule of "no but's, just and's" (every idea someone has to say "and" to, no shooting down ideas, saying "but" or debating them at all until you are done brainstorming) and came up with a giant whiteboard of possibilities for us to try out.
Our next focus is going to be community engagement. Look at the people using your app and try to be a genuine member of that community. Things like commenting on hackernews (weee!), writing blog posts about productivity, commenting on similar blogs, etc. Just be genuinely helpful, honest, and don't spam.
Also look at generating content for related projects. Try and find podcasts to be a guest on, ask a blogger if you could write a guest blog post, etc.
Either way keep your chin up and keep on trying. Don't let one competitor burst your bubble.
