i think you can develop ithinkof dotcom on a writers forum or ideas platform, but then you can think of something like ithinkof/gadgets for ithinkof depends on your skills and strengths
ithinkof.com is pretty reasonable name. it does have good potential to become a big name (depending how impressively you float it). do register .IN too to make the perfect pair.

my idea would be:
workout wha's hot and see the trends.
adopt the trend to be the main topic for your home page (50%).
provide ample stuff to your visitors about the main topic.
provide counter stuff to the main topic (25%).
keep monitoring emerging stuff and give some space on your main page (20%).
as your main topic phases out, promote new stuff (most likely from emerging stuff) as your main topic.
keep a section for old stuff on main page (5%) (showing 3 random snippets of older posts).
maintain new/old stuff in categories.
