critical thinking on podcasting

OK, I have to admit podcasts are everywhere. You can find more and more people talk about it, more and more people think they can make money from it, although some of them question it. I am fond of podcasting that helps me get information quicker. On the other hand, I treat it as the way to improve my English.

Nevertheless, I don't think podcasting will come to mainstream as soon as blog did. The main reason is how you can evaluate a podcast before you listening to it. Blogs are based on texts that we can search the key words to find out the valuable information we need then to read it. But podcasts are based on 'voice'. How can you search in 'voice' or judge the quality of it? Thus, it is hard for people to search useful podcasts and for those who make podcasts to spread his/her works. All we can do is listening to those who are already famous in blogsphere or radio broadcasting.

Maybe the alternative of podcasting will be Vlog, where people can put on their videos instead of texts, such as Microsoft's Channel 9. Today 'Google co-founder Larry Page has announced that the company wants the public to send in its homemade videos', which might boost the expansion of video blog.
