Cross blogging or reposting information from another blog/site is a natural form of compliment and considerate of another persons effort. All of us have "punked" articles by rewriting or doing a "mashup" of information from another site. When we do it politely, by giving credit and/or linking back to the original work is healthy for online communities.
In Facebook, I have been encouraging friends and associates (The Eddupunk) to "share" the original FB article rather than posting the link anew. This is actually a win-win-win situation. The original writer gets traffic and new viewers. The FB wall (e.g. My ESL Friends) who found it gets credit for finding a cool article. And finally you, as the person who shares it, get's to show your friends that you are a valuable source of new information.
Today I would like to share how to "reblog" an article in its entirety from another blog/web site. We would do this for several reasons. First point is that both of our blogs ( www.myeslfriends.com and http://theedupunk.wordpress.com/ ) encourage all to punk any part by anyone. We do not require special permission nor credit back. It is nice and considerate if you do link back but not required.
I reblog for several reasons. 1st is that some articles are pertinent to both of my blogs so copying is the simple answer. Secondly there are sites that have a narrow readership and would benefit from the info. This would be like the E-teaching forum on WizIQ ( here ). I also reblog an article which pertains to a particular event (like game on WizIQ) as the class description. You may have noticed when I do this, I add a line to the bottom of all cross blogged postings with the location and link to the original blog. This makes for a very impressive class description and implies professionalism (hee hee, little do they know ). And it didn't take additional work as I had written it for my blog already.
Recently we began using the free version of WordPress. Note WordPress dot org is the version that you host on your own server, www.wordpress.com is the one that is hosted for free on their server.) There are a lot of limitations on the free dot com site but it is free, extremely easy to use and has some nice "bells and whistles", a "reblog" button being one we will look at momentarily. You have heard me and others say how important having your own blog is for communicating in the virtual world of tomorrow. WordPress is generally agreed to be the best all-round solution.
Now to the purpose of this article (sorry it took so long ;-) ) 
If you are a WordPress "dot com" blogger you will notice a "reblog" button on fellow "dot com" sites. This one button saves a ton of steps and confusion by making the process of reblogging a worthy article to 3 easy steps. When you click on the button it asks you to which blog you want to post it. (It would be one of your "dot com" blogs if you have several. It would also ask you to write a comment. This will appear at the bottom of the copied post on your blog. This is where you would put your "two cents worth" in and add your perspective or points to focus on for your readership. 
That is all you do! On the original blog article there will be a new comment added sharing your notes and an "outbound link" which lets the original blog readers find you. This also is a good thing for SEO optimization. But the biggest plus is that you are being considerate and showing your appreciation to the original writer of the material you want to share. Finally, you will "do the right thing" by providing an "inbound link" for your readers to find the original blog. And incidentally you will be improving your SEO.
Notes: SEO is Search Engine Optimization cross blogging, inbound links, and outbound links are technical terms that I may not be using correctly. The original posting of this article can be found here: http://myeslfriends.com/wordpress/2012/01/26/marketing-with-cross-blogging/
