You have a Blog running on WordPress.com and you dislike the like button that went into your Blog by magic?
Go Admin: Apperance -> Extras and uncheck the last checkbox next the extremely long label Show a like button and who has liked my post on all of my blog posts above the comments section (Support Document). That was long. Done.
Like Buttons are lame, consider creating your own Posts and link to stuff you see fit. Put it in context. That’s called hyperlinking and a method worth to do. Professional Likers instead are Facebook Users. Looks like WordPress.com is unable to offer any true Facebook Like Button but needed to place a placebo. Not that it was me who asked for that. But I do a lot for my visitors pleasures, so I keep this one Button in remembrance and
to show my selfish self-loving nature – self liking was only buggy, not permanent (sacre bleu!).
Psst: There is a secret, but you can only get it, if you like this post. You get the secret when you click the button a second time.
