Revise Frontpage content, layout, ordering, etc.

We had a discussion about how to improve the Frontpage (please see the notes from last video-conference on nubes):

• How to order the sections blog posts, mission, services, events?
• How to improve handling of events and/or blog posts on the Frontpage?
• Revise Frontpage to a less sequential design?
• Change ordering of blog posts and event announcements (latest or last-announced on top?)?
• Should we subdivide events into two categories "registration open" and "next scheduled events"?

Any further discussion and ideas are appreciated. Please leave a note on how to improve the Frontpage. Thanks. @Normo @mdolling-gfz @schlauch @erxleb87 @frust45 What do you think?
