My favorite thing about blogs beyond the personal interactions that they afford is reading what people think about more products than I can usefully evaluate on my own. Two reviews that came through my reader lately have been true gems:
1. Mary “LibraryLaw” Minow discusses LibraryElf: My library elf – the joy and the horror
2. Sarah “Librarian in Black” Houghton tries a beta of QuestionPoint’s Flash interface: New QuestionPoint Flash Interface: LiB’s Review
Meredith “Information Wants to be Free” Farkas also does a lot of good no-nonsense reviews.
