This “织” comes from the word“织围脖”,that originally means weaving scarf. And while the pronounce of "围脖" is similar to "Weibo",so we use this word in the internet as writing the Weibo. The tenth emoticon means that sb have done a very good or very cool thing or sb performed very well. Sorry about my poor english. And I hope my answer can less or more hlep you.

I think it means i have seen.for example,you write some thing on the MicroBlog，i read it ,then i respond with this picture"织".it a chinese on line language,it sound like“吱 ” which mean squeak.I wish my poor english can help to explain this...

NOTHING..............believe me.

just a sign, forget it!

织与“吱”字同发音，后者是个发声词。有没有人问过你：听到我说的了吗？听到了就吱一声。所以意思就是听到了，就这意思。
