Random body is random, just like this screenshot.
I love faction reputations. I must fill all those little bars! Wrath had a host of factions and ways to gain reputation with them, some good, some not so much. So without further ado lets get started. (note: As always, this is from the Alliance perspective)
The Kalu'ak - This is by far my favorite faction of Wrath. These little guys manage to be cute and venerable at the same time. In my opinion this is the way a reputation grind should be done. There is an initial quest chain that tells you the story of the Kalu'ak and gets you started on your reputation grind. The daily quests are quick and relatively engaging and even spread out across different zones. For me these guys are a joy to rep up with.
Sons of Hodir - Sons of Hodir is a close second for my favorite faction of Wrath. The quest chain to become friendly with Sons of Hodir is just plain fun, full of flavor, lore, and crazy blue ladies. The dailies are numerous and varied, not to mention bordering on pornographic. I mean who doesn't giggle when completing quests named Blowing Hodir's Horn, Thrusting Hodir's Spear, or Polishing Hodir's Helm? For those who want to power through them with gold there is also the option of turning in relics or everfrost chips. A great change that they made half way through the expansion is that the shoulder enchants are BoA so that if you don't want to you don't have to repeat the grind for your alts.
The Oracles/ Frenyheart Tribe - These guys are truly hysterical. They could have just given you the daily quests, but the addition of your oracle/frenzyheart helper who likes to insult you while completing your dailies is genius. I also like how the quests vary from day to day. The only thing that sucks about them is that the Oracles get all the good rewards. It seems impossible that Blizzard didn't realize this, but I can't figure out why they would do this. However its worth doing both of them just for the entertainment value.
The Alliance Vanguard - This is a type of meta-faction under which are four individual reputations; Explorer's League, The Frostborn, The Silver Covenant, and The Valiance Expedition. Running heroics without a tabard that grants reputation will give reputation through exalted with these factions.
The Frostborn/The Taunka - Other than the fact that the Taunka are the counterpart to the Frostborn I know nothing about them, so on the Frostborn. These guys have a great opening quest line with a big lore reveal upon completion. Unfortunately the awesome sauce stops there. They offer no daily quests or turn in opportunities. The only way to get exalted with them is to run Heroics without a reputation tabard equipped. That is lame.
The Explorer's League - There is so much potential with this faction, its sad that they did nothing with it. Some quests will grant reputation with the Explorer's League, but they have no rewards or daily quests. It's probably not going to happen but I would love to see the Explorer's League tied into archeology in Cataclysm.
The Silver Covenant - These guys have absolutely zero personality and I have no idea what they are even for. However the quests you do for them through the Argent Tournament aren't too bad and the rewards are good.
The Valiance Expedition - This faction is sort of the default faction of Northrend. Not too exciting, although most quests grant reputation with them.
