Hello Eleanor37, Yes of course it is possible to find love on linkedin.
When you find some linkedin account and you liked to know them better and try your chance, type their name in a search engine and check the results. Try to find personal information on the one you like, including the marital status. Approach a potential date: If the person is single, approach them by sending a request to connect your profiles. Alongside, also send a message asking them out. I wish you the best luck.
