RSS or Real Sweet Secret of professional knowledge-sharing

SUMMARY - Now that blogs and RSS (Real Simple Syndication) are here, professionals who know how to write concisely and communicate effectively will have a tremendous advantage over those who can't.

DETAILS - Imagine there are two IT professionals, and that they both have 200 connections on Linkedin. They both read the same magazines, and attend the same industry conferences and seminars.

However, Professional A maintains a blog where he shares his growing professional knowledge with his 200 connections, while Professional B does NOT have a blog.

Furthermore, Professional A's blog has a "Subscribe" button, which enables his connections to subscribe and be alerted as soon as he writes a new posting.

Now who do you think is more appreciated? Who do you think is building goodwill and is multiplying job/contract opportunities by sharing his professional knowledge?

Professional A is perceived as a generous person, who is dedicated to his field and cares about empowering others through knowledge-sharing.

Professional B is perceived as someone who might want knowledge from others, but can't take the time to share his own knowledge to his 200 connections.

It is obvious who will advance in his career faster, isn't it?
