Do I need permission to share link of other bloggers?

Response to a Ask to Answer on Quora

Q: If I am creating a blog on Top 10 something or content aggregation/curation website, do I need to ask permission from other bloggers before posting their link?

After all I am increasing traffic to their blog!

A: Hi Yoshita, I don't think anyone will object to that. However, when ever in doubt, contact the blogger whose link you are sharing. In fact they will be more than happy.

One free advice: I don't know your purpose of blogging. But would request you to have a mission for your blog.

Blogging is not a tool for earning money as it may take years to get the traffic to earn from it.  I would suggest you to start blogging only if you are truly passionate about writing.
