I'm not a Twitterer in the true sense of the (fake) word. (Though I do tweet, sir.) ((Ahem, sorry, bad Shakespeare allusion...))
ANYway, I feel that Twitter can be a slippery slope and must be treated with the respect due to it (which is not to say that I haven't seen it used very effectively). As such, I post when I have something to say, but otherwise lurk. And I'm an expert lurker. In fact, while lurking today, I noticed a theme: people can be jerks and/or sweethearts. Behold the human condition.
So, I came up with 7 days of random acts of kindness, effective immediately. I hope it's self-explanatory, but the point is that I'm try to be proactive in my randomness, and less self-absorbed and selfish, by doing at least one randomly kind thing for someone else with no end-game other than making someone else's day better (and maybe feeling good about myself afterward).
I'll be sure to keep you posted on what I come up with. In the meanwhile, please share the random acts you've done or had done for you. It might help give me, or others, some inspiration. I just get tired of hearing bad news all the time. Don't you?
