I like numbers. They can mean a lot of things.
Rather than continuing silly arguments over obfuscated and flawed measurements of “language popularity”, perhaps a better way of measuring the viability of a language or platform is to measure the freshness of its ecosystem.
LaPerla’s How Fresh is the CPAN? measures the upload dates of one of the world’s largest and most active repositories of free software. Of the 12,000 (or is it 14,000 now?) distributions on the CPAN, 25% have a most recent upload date of February 2008 or newer. Half have an upload date of 2007 or newer.
You don’t get those kinds of statistics by putting “Ruby Programming” into Google and pretending the results are meaningful.
