Though I don't fault those who don't have interest in trying any of these, because everyone's tastes are different and it's purely personal choice as to what you drink and what I drink (which, of course, is what makes beer great, and is also why I don't criticize BMC drinkers either, though I try to coax those that are friends into the craft world... but I digress).
Here's the way I see it....
1) It isn't these guys that are exclusively saying it... they are using over 3 million ratings on BeerAdvocate to reach this listing. Thus, a lot of people are included in this ranking.
2) I personally am glad I've tasted a lot of these. They are great beers in my experience. That being said, I'm glad I didn't purchase full bottles of a lot of them, as some of these are good in small portions and for sharing.
3) To that point, I find that going to these tastings/sharings is a great communal experience. While you find a snob or two occasionally, most are there just to be friendly, share their beers, have a good time, etc. It's a great deal of fun.
4) The great thing about beer is that there are more than 100 styles and thousands upon thousands of beers to try. A lot of great stuff out there, and a lot of styles to match the tastes of each individual customers. Variety is the spice of life, as they say.
5) Dreadnaught is worth your time if you are in IPA drinker. IMHO, it's better than Pliny, but both are worth seeking out.
6) Pliny is like $5, while Dreadnaught is maybe $10. You can score a bottle of KBS or Hopslam for maybe $4, and a bottle of Expedition for maybe $2. Only a few beers on this list are splurges (Dark Lord is $20, but is very limited. Westy is not cheap, but not crazy high [I think the sale in US was $85 for six bottles and two nice chalices, so maybe $10/bottle], but is so limited you end up paying a lot for it on the resell market, etc.). That is another great thing about beer. If you want to get a super high-end bottle of wine, you're thinking $100 or much more. A high end beer is more like $20-30, and many are less than $10.
