When posting a link to an article, I occasionally find that the title of the article doesn't best describe the content, is unnecessarily link-baity, is overly simplistic, or is bombastic.
As a result, I will title my post with what I think is a more-appropriate title for the article. Most of the time these are subtle changes. For example, today I changed the article: 10 questions about Nasa's 'impossible' space drive answered to Questions about Nasa's 'impossible' space drive answered as I find listacles to be annoying, and a question count to be unnecessary.
In other posts, I added some information, changing Scientists threaten to boycott €1.2bn Human Brain Project to Scientists threaten boycott of European commission-funded Human Brain Project, and changing Sony admits defeat in e-reader battle with Amazon to Sony admits defeat in battle with Amazon, discontinues e-reader.
Most of the time these edits are fairly innocuous. However, I wonder thoughts you all might have on the matter.
IMHO, titles are often the weakest part of a journalistic piece, and as they are typically decided by the editor, and not the author of the article, I don't feel compelled to mirror them on my post. Personally, I'd prefer that my feed be comprised of titles that reflect the content behind them, and nothing more.
