I had searched and found nothing to indicate that the above had been discussed here. Short urls are used extensively on Twitter and other sites providing similar services. I'm of the view that such links do not pass link value and probably nofollow too. Some of you are probably thinking that this thred is in the wrong section. I believe it is in the right place because it is related to internet marketing since text links will attract more focussed visitors for better sales conversions. Your comments please. Thanks.
Twitter is to create buzz. Not for link building. An shorten link will not give any value to your URL. Get more followers and get more visitors.
I'm Sorry Friend, you are making a big mistake. Not "anywhere" where you can't put link is a place where you can build link (i mean link building). Twitter is a nofollow and it can be dofollow simply because in this case it'll be a junk for spammy links. Twitter and other web 2.0 is for networking, build relationship, creating buzz, go viral,....... keep that in mind friend
Twitter is nofollow, but you have to remember, there are several twitter aggregators, that will republish your "tweets" don't give up hope building links via twitter, but it is more for the "Buzz" and "traffic" vrs back links.
They've covered this on sphinn.com http://sphinn.com/story/103552 It's actually 2 slightly different issues - twitter being nofollow - frankly you can't blame them, they would be spammed to death otherwise and tinyurl being in theory dofollow, but nofollow in practice.
