I would say they have about the same meaning, though "or what" is more informal.

It began as a little curiosity. What do you think?

One year ago, I started to learn English the first because was to improve myself, before that I just knew the pronouns. Now I love it so much. Every night I study for three hours becoming the more hungry with that, the more I study the more I want to. It's fun.
Since I began to watch movies and tried to form sentences, my courage to express myself has grown. It's exciting.
It looks like my tongue gets free.
I know have so many kinds of mistakes I'm still making.
However, I won't get down or give up.

Thanks for reading my little article.

I don’t mind being dressed fashionably. I prefer buying high quality clothes that won’t be used after one month of wearing or after 5 washings. I don’t know current fashions at the moment, but I think the same brands are very popular at all times. I like wearing certain brands, like Nike or Adidas. I usually buy all my clothes and outfits from the same few shops. These shops are neither expensive nor cheap, but products sold in these shops are suitable for my style and the quality of the products is excellent. I think you can't tell a lot about a person from the clothes they wear. Although someone wears clothes made by Gucci, it doesn’t mean they are very rich. The same goes for people who wear the cheapest clothes. It doesn’t mean they are very poor. Someone might have just bought a product from popular brand a few years ago and still wears it to pretend to be rich.

Gracias, Antonio. Tiene sentido, Anita.

I'm João, I'm from Brazil. I was born and raised in Paracuru, which is a small, little town located in the state of Ceará, and Ceará is in the northeast of Brazil.

I've been learning English for 2 years now and it has been a great life experience for me.
Actually I'm still so far away from achieving my goal, which is to become fluent in English, but I'm just able to see my growth like I'm able to have great conversations in English ya know, using a foreign language and all the effort that I already have done paid off.

But sometimes I get kinda frustrated cuz I don't understand all of what people are saying in English and sometimes I don't even understand anything, but I know that is part of the process and fluency doesn't come over night, you have to work really hard on that if you really want to be fluent in whatever language that you are trying to learn.

That was a little of my language experience and I just want to share my thoughts about that to you guys!
That's all and see ya!

I'm a native English speaker. :)
