Update: I clarified the second...

Twitter poll: Do you inspect your new followers?

Category : General

I’ve noticed lately that some of my colleagues online have a very large number of followers. Not to assign them a nefarious motive, but I wondered if folks really check out followers to determine whether they’re real people or spammers. It’s a question that interested me, and just for kicks I sent it out to Twitter. Here are the 15 or so responses that came in within an hour. Looks like most folks do check it out.

    Twitter poll: Do you care who follows you? Do you look at your new followers or just let anyone follow?

  • NMHS_Principal: I try my best to block obvious spammers, other than that anyone can follow

PleaseRobMe and Geo-Location Tweets

Category : General

I’ve been thinking about PleaseRobMe. It’s a clever idea, and a clever name. But all it does it search.

So I went to their site, and figured out how it works. And I set up a search for my local area. Now I can easily see who in my local area is not home. It certainly brings the robbing me issue closer to home.

Now the question is, what do I do about it? I’m not sure I need to do anything. My thinking goes like this..

1. Most of the time I check in, I am out of town at a conference. This is obvious by my earlier tweets, anyway. Am I putting my wife and daughters at greater risk?

2. Is anyone really reading that stuff anyway?

3. Shouldn’t I just protect my updates and not worry so much?

How do you all handle it that travel a lot? I confess I like to see folks check-in. It gives me a personal flavor to their tweets. And for me, Twitter is inherently personal.
