Delhi Online is an interesting idea but its success would depend on how many resources you are able to put behind it. If you are planning to go it alone, it would be better to start blogging about Delhi using WordPress.com (for its Google optimization) as opposed to hosted WordPress. Also try to concentrate on issues not tackled by the main stream media.
If you are planning to stick to the current format, it is going to take a lot of work. In its current form, your site makes heavy use of scripting. Scripting has always had a bad name, but in today's malware-ridden Net, it is even more avoided. No wonder the most popular extension for Firefox is NoScript. What that means is that Firefox users who have installed NoScript would find your site awkward and unusable. This is another reason to use WordPress.com / hosted WordPress, your site would degrade well in browsers which have eye-candy features disabled. Another way would be to use CSS.
If you want to continue running such an extended site alone then one option is crowd sourcing. For instance, you have forums as one of the sections. The trouble is forums are not easy to get started. Most popular forums today are 5-10 years old. To start off, you can use a shout box in each section.
A more extreme method would be to invite contributors and let them host their ads on their contributions. This is how they would get paid for their contributions in a commensurate manner. The most popular blog in the world Huffington Post has many contributors. One more thing that can be copied from HuffPo is the special Big News pages it has on various hot topics. So instead of sections, you can have special pages for various issues of interest to Delhites. See
