Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, please do not add promotional material to articles or other Wikipedia pages, as you did to Quantum dot. Advertising and using Wikipedia as a "soapbox" is against Wikipedia policy and not permitted. Take a look at the welcome page to learn more about Wikipedia. Thank you.

Please examine WP:SOAP and WP:NOTDIRECTORY. Materialscientist (talk) 12:29, 4 July 2010 (UTC)

Wikipedia (WP) talk pages are written from top to bottom and new messages are thus left at the bottom - I noticed your post by chance. There are many answers. One is that some companies (say, 3M, BASF, etc) are already well known and their mentioning is not an advertisement, and some not (say, quantum dot producers). More important is though that we try to keep science article free from advertisement. Experience shows that once we start mentioning producers, the article quickly turns into a where to buy guide, which contradicts the WP purposes. Important to note is that most other articles (unless they are marked with a star) are not an example - WP is constantly improving. (PS Please sign your messages at talk pages with for tildas.).

 * Let me explain further. The links which your add at the bottom of your revert do classify as spam. Their repeated addition may result in blocking your account from editing. As to addition of manufacturers, this issue has long been discussed at the appropriate wikipedia project, and (I quote) the consensus has been not to include suppliers or manufacturers. The exception is where a compound is particularly associated with one or two companies, for example if it is proprietary technology or if it is usually known by a trade name (eg Proton Sponge). You may wish to discuss this issue at the talk page of Quantum dot or WP:CHEMS, or elsewhere. But for your sake, please stop readding what you add. Materialscientist (talk) 06:49, 5 July 2010 (UTC)
