I use several sites to pubish ideas and share knowledge.  Some are hosted and some are through blogging sites.

Hosted

I built these sites from scratch:

• www.forlanda.net – this site; the hub of all my online work
• wiki.forlanda.net – my personal wiki; mostly technical or gaming matters are what I put here

Blogging Sites

I post at well known blogging sites here:

• forlanda.wordpress.com – Techno Generalist:  bridging the tech gap for the masses
• technogeneral.blogspot.com – bridging the techno gap
• forlanda.posterous.com – is my WordPress knowledge base; it is in its infancy
• casualrunner.tumblr.com – is my running blog
• seotrainingforbeginners.blogspot.com – is my SEO knowledge base; it is in its infancy
• techsupportguy.wordpress.com – my blog for IT/Tech Support related matters; maybe others can learn from what I learn.
• forlanda.weebly.com – just another blogging site; not published though.
