mk. There are a lot of reasons, so I’ll just break it down by site.
Facebook is to chat with friends and stay in touch with cool people I don’t get to see often. Facebook is also the site on the internet that’s directly connected to my personal identity; sort of like an extension of my offline life onto the internet. I don’t know if it’s just me, but I try hard to keep online/offline life pretty separate. I hate giving out information like where I live and so on…
Twitter and some other design-related social media sites (Design Moo, Design Bump—both are sort of like Digg for designers) I started to use because in the future, I want to be able to let people know about posts I write on my blog (it will be chiefly concerned with design, the internet, and cool-stuff-finding) and I wanted to establish some kind of presence on those sites. But they’re helpful to find cool things from around the internet, and Twitter allows me to keep tabs on development for different apps and websites I’m interested…and feel I’m part of the lives of some personal friends I follow, or get a peek into the lives of others.
Fluther (well, I’ve only been here a day, but I used to frequent other Q&A sites) is because I like helping others, I like sharing my opinion, and I like talking.
But I hope Fluther for me will be a nice web community I can feel a part of…I like that there are many thought-provoking questions, and the Fluther population in general is polite and intelligent (and the grammar in general is much better than I can usually expect on the internet). I feel I need some kind of ‘home’ on the internet aside from Facebook…somewhere where I can communicate with people that are interesting and thoughtful.
It’s mostly about communicating with people, finding cool stuff, and publicity for me.
