I have realised over a period of time that in bookmarking v/s blogging – blogging would always win. The best I recollect about bookmarking & social bookmarking is Delicious.com from Yahoo and how beautiful Tag-Cloud it used to generate. But with time all dot-coms have died so has this dot-com as well.
If I find a good online resource and I would need it again in that case, I now prefer blogging about that resource and web-address. Besides me, people who are interested in similar resources may also find what I have shared or rather documented.
So blogging rocks.
