Ireland Y-DNA Project: Change default page setting to 5000 to see all results
David Reynolds collects Geno 2.0 yDNA SNP results for people who are L21+.
He has also put together a summary of which SNPs, relevant to L21 are tested in Geno 2.0, WTY etc.:

Family Tree DNA has recently changed the way is describes a position on the y-haplotree.
With the ongoing discovery of new SNPs on the y-haplotree, these new SNPs required a substantial change in the “longhand” explanation of a terminal Haplogroup. To avoid this awkwardness, Family Tree DNA introduced a shorthand version a few years ago that lists the branch of the tree and the terminal SNP, i.e. J-L147, instead of J1c3d.
Family Tree DNA will discontinue showing the “longhand” version on the y-haplotree and they will focus all of their discussions around the terminal defining SNP.
We, administrators of the Ireland yDNA Project have added the terminal defining SNP to the titles of the subgroups used in our results webpage.[added January 2013]
