We do have digital platforms for sharing stuff like that, but they are operated by the schools and the data is encrypted, access locked to the correct parties and the data is t kept forever. That way, you can actually also share meaningful information directly linked to your child.
Parents are asked whether to select whether photos can be used for
1. Inside for school displays 2. For training purposes 3. In school newsletters 4. On the school website 5. For publicity purposes, including Twitter, press releases.
I too am a parent, if the school want to say 'well done to the football team for winnning the London championships', and have a photo of the team with the trophy that's fine by me. Some parents agree, some disagree. Some disagree until their kids tell them that they would like to be in the photo.
Names aren't used on the Twitter account.
I work with a school and they Tweet out stuff bout what is happening at the school, photos of student activities, etc which parents love. They tweet out thanks to organisations that they are working with or who have come to visit. People working there follow the Twitter accounts of education specialists, regulators, other schools, education department officials etc. All useful stuff.
