The Portfolio Probe blog is caught by two blog aggregators.
Finance
MoneyScience has an aggregation of financial blogs. It now catches over 50 blogs.
R
R Bloggers captures the Portfolio Probe posts that are in the R Language category. It gets posts from over 300 blogs that talk about R.
Figure 1 shows a plot of the increase in the number of R bloggers over time. This is from Graph of the Week in the post “R-Bloggers Steadily Growing”. I’m biased of course, but I think this plot would have been better if it had used the pp.timeplot R function to make the times more visible.
