Hey, just so you know ... this post is now about 14 years and 11 months old. Please keep that in mind as it very well may contain broken links and/or outdated information.John C. Dvorak summed it up pretty well (for me) in his recent article on PCMag.com:
If I want a personal webpage with all sorts of information about myself, I’ll go to WordPress.com and make one. By doing this, I don’t turn over any data, control, or information to an onerous third party to sell, use, or exploit. I can close down the site when I want. I can say what I want. I can pretty much do whatever.
If I am the least bit worried, I can use my various providers or other services to post a WordPress blog right from my own server. None of this is possible with Facebook.
I finally broke down and opened a Facebook account … although the impetus to do so was my daughter wanted one, so I needed one to keep an eye on things.
