Thanks for all the nice discussion.
I wanna say few tips for the concerning topic here:
1) Starting a newsletter may be helpful. We may first collect e-mails of our friends, collegues, teachers, juniors, co-workers etc.
3) RSS feeds can help Search Engines to easily digest/index the content; at the same time remote syndication.
I myself, haven't used any of above technique, but for my Web site, I would like 'news' from Webmasterworld and SearchengineWorld RSS feeds (these news I know are really very interesting).
