You can bet at a dinner party anyone who yammers on with me, me, me won’t be invited again.
If all you do is talk about yourself—your products or your photography or your awards—on Twitter, don't expect many people to engage you.
Heck, this applies to anywhere you have a social media presence and yep, even your blog.
Sharing is awesome. But sharing only things about yourself and not talking with people or asking questions?
Avoid being “Twitter Tacky”.
