Hi Amit
Not aware if Drupalers use mailing list still!
Just seen an IRC channel #drupal-support on freenode IRC network, I think people can join that channel, ask support questions & expect to get answers in real time!
Whenever I need any support, I google my question as "drupal <question>" in most cases I get links of relevant issues / discussions / modules... then I do read relevant posts... in 80% cases that solves the problem... if still un-resolved I post either an issue or a question under relevant project / forum.
I feel that actively using
drupal.org resources (projects, forums, handbooks & issue queues) is the best possible way of getting support for Drupal!
