this kind formula like this: 方便不方便？=方不方便 喜欢不喜欢？=喜不喜欢 舒服不舒服？=舒不舒服 麻烦不麻烦？=麻不麻烦 It's a way to simplify words,generally speaking, people use 方不方便a lot than 方便不方便.

Maybe it's just because it was in a podcast. I find a lot of people just say 喜欢不？方便不？ instead of the longer versions.

其实这两种表达方式没有本质区别。这只是中国人说话的一种很自然的方式，习惯使用像“方不方便”这样表达。这样就可以少一个字啦！英语口语中也有紧缩形式的例子：you're,we'll......挺相似的。

方便不方便，方不方便，方便还是不方便，方便不... ...这里不好方便，还是去厕所方便吧

2-2 Such subtle problems are really perplexing for Foreign Language Learners. They are always puzzled by the delicate tones between the synonyms/ synonymous phrases about the hidden sense of Emotional Coloring, Degree, Age, Localism, Collocation and Style. Native speakers have an underlying sense to perceive the precise and exact meaning of each word or phrase so that they have no difficulties in choosing the felicitous phrasing. Foreign learners have to confront two disavantages: 1) they may not have command as many as possible expressions with the same or similar meaning. 2) they do not yet have the sense of the subtle differences between them. This kind of ability to distinguish them form each other about the subtle differences is called Language Sense. The language sense comes out of abundant and repeated touch with the relative expressions appearing on the same/different occasions. When native speakers find a word or phrase repeadedly occurs in the same context and conveys the same meaning, they form a concept/notion that the certain word/phrase has the certain meaning, along with the incidental connotations. For foreign language learners, owing to lacking the target language environment and frequent touch with and practicing it, it is quite hard a task to get to the same achievement as native speakers. In this sense, a western translator advised Chinese translators never to try translating Chinese literature into western languages--just translate western literature into Chinese and leave the opposite work to western Chinese speakers. His opinion is obviously somewhat dogmatic but undeniably makes some sense: according to his idea, a foreign language speaker can scarcely reach the level at which the language is mastered by the native speakers. Another involved problem is there have always been some wording way created by foreign language learners which is grammatically right but sounds odd to the native speakers, hence they avoid using them. For foreign language learners the ways and means to overcome this problem is touch and use the target language as much as possible. Trial and error does seem to an obvious crack way to learn foreign languages but may be the most effective one. Italki. com is a good stage for foreign language learners to practice trial and error.
