There is no need for apology, because Hubskina should be nobody's bag, unless that bag happens to be for the garbage. This is the first time I've been on a website where people think I'm a power-user. That's almost offensive because it implies that I don't have better shit to do (no offense, ya'll). Rescuetime tells me I average on about 1 hr 20 min a week on Hubski. It's not like I sit down, swipe my card, and clock in for "Hubski time". I don't even comment all that often. I hit about 10 comments a day at my most active. I share maybe one thing a day, and the only OC I post is a meta-narrative-fanfiction about people I've never met in real life. About once every two weeks. Who watches the watchme-I mean, power-users.
I like it. You can define every website and app on a scale of productiveness, from 'very distracting' to neutral to 'very productive'. It's accurate. I have the premium version and it gives me lots of sexy graphs and whatnot. Really it's most worth it when you have the premium version. The free version is good too, though.
