Basically submitting your blog XML sitemap into Google with the help of webmaster tools will improve and quickly index out your blog by the Google search engine.
I checked your site on google by typing site:thenetinformation.com and it showed me some 633 indexed pages, maybe you need to wait a little while for it to show on webmaster tools
what i do to make my site indexed fast is bookmarked all my pages using socialmarker then ping every bookmark using pingomatic. works all the time for me.
Your site has quite a few pages indexed by Google, if you are worried though try getting some inbound links and fix the xml sitemap, which doesn't seem to work.
you are submitting Sitemap to Google for Faster indexing of pages.. there is another Way through which you can index your page and you will get traffic too.. try submitting your non indexed URL to bookmarking Sites.. it drives traffic and index page soon.. just select 10-15 High PR bookmarking Site.. and Submit you URLs there..
for a post that is not the index, try to post on another site. try to type in the google search engine sites: thenetinformation.com
