After we installed the free program and chose the services we wanted, we opened Windows Explorer and noticed a new item in our list of folders.  Clicking “Social Folders” revealed a folder for Facebook and one for “SmugMug.” We’d forgotten we have photos on SmugMug, and there they all were, from eight years ago.

Social Folders connects to Picasa, Photobucket, YouTube, Box, Flickr and Google Docs. It manages 2000 files for free. After that, it’s $2 a month or $10 a year.

LOL is texting shorthand for Laughing Out Loud; OMG is a common abbreviation for Oh My God or Oh My Gosh. You see them all the time in phone messages and social networking.

It’s ironic that the founder of the website “JuicyCampus.com, “(a site since taken down), has now written a book warning of the dangers of social networking. The book is aimed at high school and college students but has good lessons for anyone.

Some of the consequences of online behavior: A junior at UCLA dropped out of school and received death threats after his YouTube post described Asians at the library. A freshman at Rutgers is facing criminal charges after his roommate reacted to a video by jumping off a bridge.

The book motivated us to purchase a couple of new domain names, BobSchwabach.com and JoySchwabach.com, both of which steer you to our main website. The author says most people should own a website in their name, just to prevent someone else from getting it.

If you see the word “required” next to a site or app, that means you can’t edit its settings. But you can delete the whole app.

It’s a free Facebook app called “Say it with Skype.” Type in a friend’s first name and get a choice of Facebook contacts with the same name. Then choose a rock group. We hadn’t heard of any of them, but then again we’d undoubtedly fail any pop-culture quiz. They’re supposedly well-known: Bowling for Soup, CSS, Parlotones, Imogen Heap, Ash, Charlie Simpson, Body Language, Scarlet Grey, and Kill the Young. At the end of the video the group will hold up signs saying “Happy Birthday Judi, from Bob and Joy,” or something like that.

When we chose the sing-along option, we saw ourselves singing in one of the four video panels, the others being filled by celebrities we never heard of. If you don’t sing along, your Facebook profile photo is displayed instead. You don’t have to do anything with your creation. But if you want to share, it takes one click to post it to your friend’s Facebook wall. You can also copy the link and add it to an email.

Go to Shelby.TV and sign in to your social networking accounts. You’ll see a list of videos posted by people you know. Play them or share them, they’re all there. In this way, we discovered a video by a member of our Second City “improv” class and a musical engineering flash mob posted by Kno books. Fun.

Facebook now has about 800 million users, which is slightly more than the whole Internet had in 2004, according to InternetWorldStats.com. The Internet now has over 1.7 billion users.

According to a Wall Street Journal survey, seventy-three percent of iPad owners have a phone that is not an iPhone. So how do they get their iPad music to their phone?

We’ve been trying out “MyMusicCloud.com,” a service that lets you listen to your music on any Internet device, including smart phones and tablet computers. A great feature here is you can click a “lyrics” button on the screen and see the lyrics for that song. These can be copied and pasted into Word or email, if you like.

The service also lets you create ring tones, listen offline and let Facebook friends know what you’re listening to. You can store only two gigabytes of music for free, but you can have five gigabytes for just $10 a year. Amazon’s “Cloud Player” gives you five gigabytes for free, but it doesn’t have that nice lyrics feature.

– Posterous, formerly a blogging site, has reinvented itself as a social network called Posterous Spaces. Here you can share audio, video and photos just with certain circles of friends without worrying that anything travels beyond that circle. It’s at Posterous.com.

– Another way to go is “Elixio.net” which claims to be a site for movers and shakers. We were a little shaken by event listings: like “International Workshop on Folk Dances of India” and a “VIP party in Abu Dhabi.” There are hundreds of special interest groups in such categories as “Finance,” “Art” “Luxury” and “Film Industry.” There were also unusual (to say the least) ads in the classified section, such as one looking for an investor to open a punk rock club. If you want an invitation to this  send us an email. We have 24 of them.

– Back to Facebook. (Who can ever get away?)Their new “smart lists” automatically groups friends from high school with you in one list, friends from work in another, and so on. You can do this manually but it saves a lot of time if you have hundreds of “friends.” This feature hasn’t rolled out to everyone yet. Another one is “subscriptions.” Decide if you want all of a friend’s updates, just the important ones, or just the ones in certain categories. Or follow a celebrity’s posts, without having to befriend them.

–Back to GooglePlus. (Apparently, a lot of people aren’t going back.) After huge publicity, public posts are down 41 percent since August, though some people are as prolific as ever. Guy Kawasaki can drive you nuts, for instance, because he does about a dozen posts a day. But they’re great.  Update: Since opening itself to the public last week, Google Plus has soared to 50 million users. No more invitations required.

If you thought Farmville was hot stuff, wait till you try Zynga Adventure, a new Indiana Jones-style game that will send you looking for the lost city of El Dorado as you traverse jungles, mountains and temples.

The game is 40 times larger than other Zynga games and involves 200 quests. You can ask friends to join your crew and help solve puzzles, get out of traps and avoid snakes. No word yet as to availability, except that it’s “coming soon.”
