4. Post on MySpace Profile: Don’t forget about the world’s second largest social network when sharing your favorite articles. Post the link to your MySpace () profile so your friends can enjoy it too.

5. Posting to LinkedIn: Some blog posts are worthy of being shared by your business network on LinkedIn. Post a link to the Network Updates area in the homepage.

You can also add notes and comment as well.

12.

They are the quick and easy versions of full-fledged blogs, ideal for posting about pictures and blog posts.

13. TwitThat: TwitThat is one of the quickest and easiest tools for sharing blog posts. It will post to your Twitter quickly and easily. Just add the bookmarklet to your browser toolbar and click it whenever you come across a great post.

15. Ping.fm: If you’re a busy person, you might not have time to share on all of these social media websites. Isn’t there an easy way to share a blog post everywhere, all at once? Ping.fm links to all of your social networks and sends your updates to LinkedIn, Twitter, Facebook, to any other website you wish to link to it. You can even update from your instant messenger. It’s the perfect solution for those who like to share content all over the web.

16. Emailing: Email has always been a good way to share articles, especially with close friends and family. Although it may not reach as many people as Twitter, it will definitely reach anyone who isn’t as deep into social media as you are.

17. Texting: Did you know you that many blogs, including Mashable (), support sharing an article via text message? Look out for the ShareThis button (three green dots connected by lines) under blog posts and select the “text” option. iPhones and mobile browsers have made it easy to read links sent by texts.

18. Changing IM Statuses: You probably have dozens, if not hundreds of IM contacts. Share great posts with all of them by changing your IM status to a great post you just read or wrote.

19. IMing a friend: If changing an IM status seems too impersonal, then just IM your friends the link. You can then have a fun chat about the blog post.

20. Talking to Friends: If you don’t have a computer handy, then don’t forget about the analog approach – call a friend or tell him or her over coffee about a great blog post you read. You can always send the link later if necessary.

Google just announced a new service called Google Voice (click here for Mashable’s story).  According to Mashable:

The service looks a lot like Gmail
for voicemail, although you don’t have to be a Gmail user to use it. It lets you retrieve transcripts of your voicemail, archive and search all your sent and received SMS messages, and you can make calls directly from Google Voice’s interface. The calls are free in the US, and cost a small fee internationally.

You can call Google Voice and leave yourself messages.  Google will automatically transcribe the messages into text and email them to you!
