Q. I have a Facebook etiquette question. If someone from my past asks me to be her friend on Facebook, should she send me a message after I accept her friend request ? I have had quite a few old friends ask to be my friend on Facebook, but after I accept their friend requests, I don’t hear from them again. This makes me feel like they are just trying to increase the number of friends they have on Facebook. Am I supposed to send them a message on Facebook first? Please help!
A. I can understand your concern. No one likes to feel used and if someone friends you on Facebook and then you never hear from her again, you might feel that way. But there is nothing wrong with you reaching out first. Try sending your friends a message and see if they respond. If they don’t respond and you feel used, you can always unfriend them. If they contact you after you unfriend them, you can always explain why you unfriended them.

Q. You mentioned in the StumbleUpon blog that I should close the app (see, You’ll Fall for StumbleUpon!). How do I close an app?
A. This is a great question. Many people think that by leaving an app they are closing an app on a smartphone or a tablet, but they aren’t. The app will continue running in the background. This uses memory and makes your battery drain faster. You could even be using data and going over your data limits after you leave an app.
You didn’t mention which smartphone you have, but if you have an Android phone, you’re in luck. There is a free app in the Android Market called Fast Reboot that will close all of your open apps for you. If you want to close individual apps, you can buy the Fast Reboot Pro version of the app for $1.37. After you download Fast Reboot to your phone, click on the icon and it will close all of your open apps and tell you which apps it closed. Do this twice in a row. If you find apps are open the second time you click on this app, then you have apps that are automatically running in the background.
To make sure that apps aren’t running in the background on your Android phone, go to Menu => Settings => Accounts & Sync and unclick Background Data. You will find that your phone will run more smoothly and your battery life will be longer when your apps aren’t running in the background. Make sure you put Fast Reboot on your home screen and use it often to close all of your open apps.
For iOS devices, iPhones and iPads, double click the Home button at the bottom of your device. A bottom toolbar will appear showing icons of your open apps. Hold your finger down until the icons jiggle and the red circle appears with the minus sign. Click on the minus signs to close the apps. Don’t worry, this will not delete the apps from your device. The apps will not be running in the background until you open them again. Your device will run more smoothly and your battery life will be extended when you take this extra step to manage your memory.
Q. Sometimes I do a Google search and it takes me to a page where I can’t find the words I searched for. Is there a way to have Google take me to the place on the site where my search word appears?
A. To search for a word on a web page, use the Find shortcut by clicking Control + f which brings up a search box at the bottom of your screen. Type your search word into the box. As you type, you will see the letters highlighted on the screen. You can stop typing when you find the word you are looking for.
The words “nostalgia” and “tech” don’t usually belong in the same sentence, but in the case of a new iPhone app, the words mesh perfectly. Atari has launched a new app in the iTunes app store called Atari’s Favorite Hits that brings 100 different retro Atari games to your iPhone or iPad. The app is free, but you need to buy the games for $.99 each or $14.99 for the entire set. If games like Centipede, Missile Command and Asteroid make you yearn for days of old, head over to the iTunes app store and grab the free app. Bonus: If you want a more realistic arcade experience, check out the iPad case that turns your iPad into an arcade game from ThinkGeek.
