The directory is quite old -- 22 months and my partner has been developing it ( I'm the promoter/admin/editor) We have been developing it very slowly - as both have been pre-occupied by other projects. We have kept the prices at very reasonable level - as our main aim is to make a quality leading resource site on Technology and Science Web Directory niche. Regular review prices only - $11 (no top categories allowed - please submit to the closest sub-category) Featured review prices - $25 Naturally - unrelated sites will not be accepted and rejected. We will approve only sites related to the topics. Submit URL here .
