Science 杂志的online comment 是什么东东？
在Science杂志上发表一个online comment ，和在其他杂志上（比如BMJ）发表一篇response letter相比，哪个更划算？
Thank you for sending a "Letter to the Editor" to Science. We have read your contribution but will not be able to publish it. We invite you to leave an online comment instead. To leave a comment, go the http://www.sciencemag.org and find the published paper to which your comment refers. Then click Leave a Comment to submit. Online comments should be no more than 300 words. Excerpts from comments are occasionally published in the print Letters section of Science.
If your comment does not refer to a paper published in Science, then the online comment option is not available.
Please do not reply to this email, as it will not be read by Science. Unfortunately, the volume of submissions precludes specific discussions about individual submitted letters.
