"Using Compete.com for 4 other significant technology Blog services we get some interesting numbers. TechCrunch should be valued at between $200 and $450m; GigaOm at between $46 and $55m; ReadWriteWeb at between $63 and $65m and Venturebeat between $50 and $53m. I'd say a merger between these 4 would bring them collectively up to about $350-500m even without the synergies and growth prospects of being one."
