Nice troll, but there are a <i>ton</i> of websites being developed in Ruby/Rails these days. I don't think it's nichified at all, and the number of job ads is going up, not down.<p>Ruby is being improved and sped up too, in case you hadn't noticed.<p>As always, use the best tool for the job. For an awful lot of small business sites - where PHP got its start - that is now Rails, and it's slowly emerging in larger projects too. I think Ruby will definitely give PHP a run for its money in the fullness of time.
