Use it on your wireless devices (e.g., Facebook for Blackberry app , or Facebook’s own mobile app .
Go to the main mobile section within Facebook which shows how to upload content from your mobile device to Facebook, receive content from others on your mobile, or just browse Facebook from a mobile-friendly browser interface.
Twitter can be run through your Facebook page, too
You can find friends’ mobile and other posted phone numbers under Phonebook tab
Focus your incoming content feeds on things of interest to recruiters (more about groups, and more about profiles)
Similarly, you can control what friends see about you
View job-related apps by recent or overall popularity; can find other apps by keyword
Create your own MySpace page free (prompted to do this when you create your account)
Friend Updates : your friends can be updated when you join a group, post or reply in a forum, add a video, install an app, get tagged in a photo, create new friend categories, become friends with a band, filmmaker, comedian or brand, etc.
Blogging is possible, but the blog groups are too scattered to be worthwhile.
Twitter is a free social networking and micro-blogging service to send text-based posts, up to 140 characters long (“tweets”) to the Twitter website, mobile devices, etc., via short message service [SMS], instant messaging (IM), or a third-party app. You can find candidates, useful tools, resource sites, etc. See blogpost by Jason Buss for Twitter benefits
Create a free account at Twitter. Include a laundry list of appropriate keywords in your profile that people would search on.
In the "What are you doing?" box, use links to URLs if it’s not short. Use TinyURL.com or an equivalent tool. By default, that is a public tweet anyone could potentially find.
In the right-hand column of Twitter’s homepage, you can see your numbers.
Click Find People atop Twitter homepage, you can type a skill term or job title (not just names), and maybe narrow by location, e.g., "software engineer" "new york" or J2ME Boston, but it's best to use Twitter's Advanced Search to target your criteria. In the results, you can click the Follow button beside any person to follow that user if not protected status.
Another way to find relevant people on Twitter is Twitter Tracking . You can type keywords of interest (e.g., a unique business or technology term/phrase) and whenever someone types that in an update (across the entire Twitter network, not just who you're following), you will get a message.
Great examples of how to search Twitter from posts about Summize (now Twitter advanced search) by Shally Steckerl and Jim Stroud that go beyond simple keyword/phrase searches:
geographic search: you can combine keywords with a person's cited location - e.g. (note use of boolean) near:Boston sql
type a conference name to find people talking about that conference (who are likely attendees or panelists)
type the phrase “I work for” followed by the name of a company (e.g., this has some posts from Microsoft employees).
Among the comments to Jim's post was a great tip from recruiter Michael Specht: “Most tech conferences [and] on Twitter folks have begun using hashtags [# plus keyword] to indicate the discussion going on at the conference. So search for #ConferenceTag and you get all of the [conference] gossip.” (e.g., #pubcamp).
