Back in January, B$ Operation Potent Wind went into effect, driving share prices up far higher than we'd seen in the game previously, in one of the stated purposes was to increase blog values. By March, top blogs had values of hundreds of thousands of B$, some into the Billion B$ range, including some blogrolled ones, as noted by charts in early entries here. Sadly, the math at that point was not well understood, and values could not be maintained.
We are a ways to go yet before seeing blogs hitting the Billion B$ mark, but the various blogrolls in the game are chugging along nicely, with values in the low hundreds, the Top 100 blogs filled with blogrolled sites. The top 5 blogs have even been encroached upon, and we may be only a week or so away from the #1 blog being replaced.
More sites continue to link together, wheels within wheels. So far the B$ market index graphs have seen little impact from Project Bootstrap, but a small upward spike can now be seen on these graphs. I'm taking this as a promising sign.
