probably extract most of @ciarand's app.net posts (you'll need a token)

extract.sh

#!/bin/sh

curl -q -H "Authorization: Bearer $AUTH_TOKEN" \
    "https://api.app.net/posts/search?creator_id=45708&count=200" > tmp.json

while true
do
    MIN_ID=$(jq < tmp.json .meta.min_id | sed -e 's/"//g')
    jq < tmp.json '.data[].text' | gsed -e 's/^"//' | gsed -e 's/"$//' | gsed -e 's/@\w\+ \?//g' >> ./posts.txt

    curl -q -H "Authorization: Bearer $AUTH_TOKEN" \
        "https://api.app.net/posts/search?creator_id=45708&count=200&before_id=$MIN_ID" > tmp.json
done
