The Web is made up of links, which is further carried out in the BLOG world, and becomes an incumbent behavioral specification. You reference someone else's articles, or learn something through others, you should give the original link. There is also a link, not in your article, but appears on your Blog's navigation bar, you will put some of the BLOG you interested in your website and others, that is, called "blogroll" That part. The exchange link is usually said to exchange the link here.
Everyone is in their own blogroll, there will be my own principles (there is no principle is actually a principle, anyway, you can't put 1000 links there, let your own blog really become hao123.com or 265.com). However, the principle is generally placed in his own heart, and does not publicize everyone, so when others ask for the link, if you don't want to exchange, you will face a trouble, because you have to explain why not. Explain that it is better twice, more, you are annoying.
Today, I read D. Keith Robinson's article My Link Exchange Policy, I have a heart. He lists 7 principles, I very agreed 4:
I generally don't exchange links. I found the website and article I found, if I want to link, I will take the initiative to link. I Find Sites and Articles I Want to Link To On My Own. I don't mind someone asking, but don't expect my answer. I don't mind present a reply. If you have a blog, I hope I can understand, cool, but I will first see if I decide whether it is linked. Don't harass me for this. If you have a blog you want me to Know About, Cool, But I Want To Read It for awhile before I decide to link to it. Don't bug me About it.
Live here, you can have a lot of tongues.
