I knew about E-How, but I don't remember a time when E-How had followable links of SEO value. As long as I can remember (which isn't very long -- I don't know what day it is half the time lol), they have had nofollow on reference links. So, I never gave them a second though. However, I do occasional snippet searches (for my content) or random searches for my company name, and E-How always shows up more and more. Portions of my content are ALWAYS getting used in numerous E-How articles, and they list my site in their References with a big NOFOLLOW on the link. RUDE.
In my opinion, if your content is good enough to be duplicated, it's good enough for Google to count the duplicate as a link...it should be a quality signal for YOUR site (particularly if your site is listed as a reference, irrespective of a "nofollow").
Examiner also adds nofollow on links AFAIK.
Back to E-How, and a a discovery I made yesterday...E-How is now allowing links to .gov sites in their Reference lists to be followed. You can check this by looking at some of the E-How Money pages about taxes (since they link to government documents, etc). The other sites they took information from (like mine) still get no link juice. The change is new. I have a feeling if we start to see E-How drop a bit in ranking, it could be due to this link change, allowing some of their PageRank to flow away from the site. We'll see...
And for what it's worth, I always liked Buzzle. I was surprised to see them on the Sistrix list from Panda 1. They have a fairly strict editorial process.
