I've read the post on Blizzard's web site. It only mentioned about gaining passive points as you gain Paragon levels. Does Paragon level give any other benefits in Paragon 2.0, such as increased Magic Find?
No, Paragon levels no longer provide a bonus to magic find. You can spend paragon points to increase your gold find, but it has no impact on your magic find.
Magic find can only be increased by the +magic find% affix on items, follower items, a topaz socketed in the helm, or from the implicit bonus to legendary drop rates from Torment tiers.
Note that magic find is much rarer as an affix, and has had its effectiveness in general severely diminished:
Per Travis Day (emphasis mine):
It appears that magic find has been removed entirely from the affix tables for rare items, and now only exists on legacy (pre-2.0.1) items, and select legendaries. (Source: diablofans).
Edit: Note that a recent hotfix (4/3/14), changed Nephalem Rifts to provide an additional 25% chance for Legendary items to drop (stacking with the bonus from Torment Tiers, if applicable).
Paragon levels no longer provide bonuses to magic find (or even passively increasing gold find - though you can put points into active gold drop increases).
The only direct relation Paragon levels now have towards magic find is the ability to increase the efficiency of your character.
Combined with better gear, higher paragon levels increase your character efficiency at higher levels of difficulty which in turn equals harder monsters & better magic find.
Aside from that, +magic find affixes (which are now slightly harder to come by) and certain gems will still increase your magic find.
