So Harry Hubski has been here a while now. He has tag settings.

- Follow #technology

- Ignore #3dprinting

- Follow #MIT

- Ignore #gizmodo

- Ignore #newhere

He also has some user settings.

- Follow Arnie

- Follow Bob

- Follow Charlie

- Mute Dave

- Mute and ignore Elvis

- Mute and ignore Frank

So let's say he's got his "affinity" slider set to "iron fist." Ronnie's post is going to be invisible to him - he's ignoring #3Dprinting and #newhere.

Let's say he's got his "affinity" sider set to "iron fist in a velvet glove." Ronnie's post might show up because while he's ignoring two tags, he's following two others. It's a spectrum, after all.

Now let's say he's got his "affinity" slider set to "velvet glove." Ronnie's post is going to show up in his feed for sure - while there are a number of things he's ignoring, there are a number of things he's following.

Let's make it interesting. Let's allow me to "train" the engine. I adjust my "affinity" slider and new things pop up. Some I like, some I don't. I x out the ones I don't. I move the slider some more. I x out the bad ones some more. I fiddle with that thing every day - and I'm giving Hubski input on what "affinity" means for me.

It's all data points. What matters is what you do with it.
