|What are you going to do when it melts? Eh, Ethel?|
When websites began asking folks to log in with their Facebook or Twitter account(s). I cringed then, and still do now. The situation creates an uncomfortable feeling of being out in cyber space farther than I care to be. (Yes, bloggers can be shy-ish.)
The dilemma is many websites depend on ads to generate income. We support websites by visiting them. The majority of ads I see are all right. I understand ads can't always match the post they appear near. A post of your travel photos, for example, may not be where you want to see an ad for a medication to adjust your bowels. Algorithms aren't perfect.
Participate. Search your name on a few browsers, and into a few page results. Get a feel of where you and the Internet are. Be proactive in setting your cyber boundaries as much as you are able and/or is available.
