bgp best practice question

[jon Heise <jon () smugmug com>]

I need to make one of our data centers internet accessible, i plan to advertise a /24 out of our existing /22 network 
block at our new site. My question is for our main datacenter, is it a better idea to continue to advertise the full 
/22 or advertise the remaining /23 and /24 networks ?
