Twitter has begun offering an embeddable button for one-click subscription to a Twitter account associated with any website, called the Follow Button. Previously, a website owner could link to their Twitter profile page off-site but users had to visit that Twitter page and click to follow the account from there.

Users interested in subscribing to updates from a website itself can, as always, subscribe to the Really Simple Syndication (RSS) feeds offered by many sites for years. Those are the orange buttons with the little white lines on them, and without the word Subscribe. RSS requires the use of a different application, called an RSS reader, where a user is probably less likely to encounter poorly written little jokes or the daily ennui of Hollywood starlets. Or your mom, who is more likely to Tweet than knowingly publish an RSS feed.
