# vutuv

Many people call vutuv **the LinkedIn of the Fediverse**: a free, fast and
open source social network for the profiles of humans and organizations. It
began as a LinkedIn alternative and picked up the good parts of X and
Facebook along the way: posts, likes, reposts, replies and direct messages.
And it federates, so members can be followed from Mastodon and the rest of
the Fediverse (ActivityPub, opt-in per member). The reference installation
runs at
[vutuv.de](https://vutuv.de); **anyone can run their own** — on the public
internet or inside a company or organization intranet.

## What it does

- Private messages reach accounts on other networks, in both directions, and
  live in Messages beside your conversations with members: write from a remote
  account's page, or answer a private reply where it arrived under your post.
  Text only, up to 5,000 characters, delivered to that one account and to
  nobody else. Somebody you do not follow lands in Requests, as a member would.
  A private answer under a post stays there and also opens a conversation, each
  view linking to the other.

- A public post's reach analysis is public too, uses cached NodeInfo to
  show community size when available, and is available from its
  three-dot menu. It shows the distinct people with visible interactions,
  a shareable server-network card, cached follower totals for potential repost
  reach, and three-hour interaction momentum over 7 or 30 days (daily over one
  year). Potential repost reach leads the analysis, immediately followed by
  the server network. Its larger server graph
  numbers visible interactions, uses radial labels, and arranges first
  reactions as a time spiral without claiming unobservable repost hops.
  Chart periods count back from the present and are labelled accordingly.
  Shared analysis links use potential repost reach as their OpenGraph hero.
  A separate note explains that the true Fediverse reach cannot be measured.
  Empty chart tails stop two days after the last visible interaction, while a
  later wave remains visible. Visible interactions are clearly separated from
  view counts.
- `/system/investors` adds up that potential repost reach for every public post
  of the last 12 months, and shows the calculation's steps live while it runs.

- Public member profiles (work experience, education, spoken languages, publications, tags,
  links, contact details, online messengers with click-to-chat deep links) with
  follow relationships, posts, likes/reposts/replies and
  1:1 direct messages — all real-time (Phoenix LiveView) where it matters.
  Members can also **follow a tag** to pull its posts into their feed, interact
  with posts found through that tag (fetched only when they choose an action),
  and get matching people suggested. Adding a new CV entry (job, education,
  certificate) can optionally notify your followers — your call per entry,
  in-app only, and switchable off by whoever rece
