Here's something that I think all of Team Hubski is missing:

The customization you guys are pushing requires more mental overhead from me.

To make it work my way, I have to have a conversation. I set something up. Someone wants to look at it, they click it. Done.

To make it work your way, I have to write #tag.modifier and in order for users to get my functionality out of it, they have to follow #tag and ignore #tag.modifier.

It's like that list thing: in order to make it work, I have to remember where to put the colons and shit on the arbitrary six digit string that Hubski generates with the nomenclature that makes Hubski happy. Yeah, neat feature but I'm already suffering under Hubski's arbitrary (and often broken) markup. Now you're going to make me learn site-specific nomenclature?

It's a very mk-up approach - "I can alter the codebase so that when I type this secret incantation things change." Except most of us don't want to carry a spell book around with us. We want to press the "up" button on the elevator and get to the 5th floor. We don't need to remember that typing 12356 in the stairwell keypad opens a secret passage to the dumbwaiter.

Personal tags are not something I see any need for. Sorry. They're a voluntary way for an individual user to restrict things that works only if both the user and the viewer have perfect understanding of the functionality. The site needs to be easier to get around on, not more complex.
