If you want to overcome introversion and develop peoples' skills, it is not enough to "talk a lot and say nothing". You need to feel comfortable and confident, adapt to the speaking style of others, react to their communication cues, etc. Read a lot about body language, listen to how other people speak, and start trying to imitate some phrases and topics. Besides, learn a bit about different topics you would usually not speak about, you don't need to know a lot to be able to keep a small conversation about sports, cars, gardening or literature. And if you include those topics in your small chat, you will eventually learn more. Have small chats with the janitor, the store cashier, the taxi driver, etc. Smile and be kind, people will generally be kind to you as well. There are advanced courses on oratory, public speaking and the like, but you probably need to feel confident with the basics first.
