backlinks from blogs and forums will usually lose value over time because they come from pages that gradually get pushed deeper into the site
Given that the assumed "degradation of signal" is a function of WP's software design, and not any form of conscious downward weighting by the linking authority/site, I would call the engineers or algo artists who programmed such a downward weighting of blog links . . a bit . . lacking? :P
If there is such a "blog link effect" then it's a flaw which likely needs fixing . . in algo tweak #103,483.
