I have created a blog in blogger.com and published my posts in that (http://dhanabalakrishnan.blogspot.com). I just want to know how can I ping my posts to make it appear on the Google search. What is wordpress? Is it a blogging site? Is it possible to ping my posts using wordpress, though I have created blog in blogger.com? I know it is an absolute stupidity to ask such questions, though I found no other way. "One who asks question is a fool for five minutes; one who doesn't remains a fool forever".
Google will visit your site without any pings or pongs. Check your stats to see how ofter they visit your site. Most people like Wordpress more than blogger, sort of the ping/pong thing. 11 hours and nobody answered your questions, welcome to the friendly blogging area of DP!
Generally if you want to ping your blog faster, you can do that through blogsearch.google.com/ping And about wordpress, yes its a free blog hosting site with many features advanced than blogger. Its worth a try to use.
