They give you 12 hours to transcribe one hour of audio not accounting for number of speakers, quality of audio, etc. This is all right if it is only an hour or so. However, if it is a three hour audio file you only have 36 hours to transcribe it. They don’t account for time to sleep or rest with the longer files. I did contact them about this and got no response.
Bloggers are typically people who enjoy a particular topic and enjoy writing about it on a semi-regular to regular basis. If you have something you are passionate about, or are an expert in a particular area, you can consider starting a blog. Blogs are a great way to: teach people about a particular skill, entertain, or share about life experiences.
