i'm not reading an 18-page thread, but i finished this last night and it was AWESOME. kudos the Mack and Wardilmore for this last pair of novels being so awesome.
the only complaint i have regarding Vanguard is that it skipped ahead a lot. i would've liked it to last longer by taking more time to cover the time period, but i guess if there wasn't much significant going on in the time periods that were skipped, this is not surprising. i just remember Mack saying in one interview at the beginning, that the plan then was that not every book would focus on the meta-genome mystery... plans change, i guess...
