Talk to me about how you manage your online 'presence' (if you have one)

OK, I know presence is hardly the best word for it, but I'm hoping you can solve my dilemma.

Incidentally, if you don't use Twitter, and are not remotely interested in the many and varied ways of accessing social networking, it's probbably worth closing this window right now. This is a really boring blog post. I have some gorgeous Liberty print projects coming up next week, come back for them. Please. Thank you.

Back to the dilemma.

I have a dilemma (have I mentioned that? Dilemma is such a great word, and I hardly ever have cause to use it, so I'm making the most of the opportunity), and I have spent far too much time (about 3,000,000 hours), money (£6.99 in total, which is too much in my world) and energy (well, the amount involved in sitting at a computer clicking a mouse) in trying to solve it.

I like Twitter. A lot. And I use it a lot for my business. If you follow me, you'll notice I tweet a reasonable amount most days. I think it's a great asset and I love all the interactions with people across the world who are interested in the same kinds of things as me. I intend to start up a second twitter account (despite having been very disparaging of multiple Twitter accounts in the past) for my new business venture, which I promise to get round to telling you all about in the not-too-distant future. I am so excited about it.

I also like Facebook. A little bit. I don't update it at all, but I like clicking on and seeing what my friends are up to every now and again.

I also like Google Reader. A lot. I follow something over 100 blogs, and I love keeping up with each and every one of them.

And so, we come to the dilemmas (well, dilemma really, but I've divided it into sub sections because we all know I like a good list, and one dilemma doesn't make for much of one):

1. I need a desktop application for Twitter that allows me to see my timeline and replies to me.
2. I need that application to be able to schedule tweets
3. I would also like the application to integrate with Facebook, but I'll live without that
4. I need the application to support multiple Twitter accounts for the aforementioned multiple account situation
5. I'd like to be able to see those twitter accounts in different columns at one time, not have to click between them.
6. I'd like to be able to post to either account without having to change loads of settings
7. I need a desktop Google Reader application (I'm lazy, I don't open the browser window and go there. I'm sorry). I can live with this not being the same application as the Twitter one (although in an ideal world it would be)

In my efforts to solve this I have tried:

1. TweetDeck - it's good, but does anyone else feel it's lost a lot of functionality in the last year? Saying that, I do keep coming back to it, as it's the only one that allows me to see multiple columns, pending tweets and replies all at one time. I haven't looked at the multiple account option, but I'm imagining it will work as just another column, and I think you can just select which account you want to tweet from. No Facebook or Google Reader access, as far as I'm aware
2. Hootsuite - I can't even download the damn thing. Apparently it's quite good, but three days of repeatedly staring at a loading screen have put me off for life. Apparently it's not an uncommon problem. Sort it out toot sweet, Hootsuite
3. Socialite - I imagine this would be a great way of using Twitter and Google Reader if I was exactly that, a socialite. Unfortunately it has no option to Schedule tweets or see multiple columns at once. Wasted £6,99 finding that out instead of reading all the product information. Whoops.
4. Echofon - too simplistic. Possibly good if you don't want your twitter dashboard cluttering up your desktop
5. Seesmic - such potential, but has a major bug in the Google Reader plugin thingie which means that your Google Reader column is wiped every time you close and re-open the application, so you have to go through signing in and loading the column again, slightly defeating the whole convenience aspect. If you don't want to see Google Reader, it's a good alternative to Tweetdeck though, I think

Solutions I haven't tried yet:

1. Twitterific - I get the feeling this is another single column one, requiring clicking between accounts. No good
2. Janetter - this looks similar to TweetDeck and very pleasing to look at (lots more display options), but I don't think it has a schedule tweet function
3. Sobees - still in Beta, and I'm not sure I can be bothered (does anyone remember Pinterest in early Beta stages? Horrible. Everyone should follow the example of Ravelry and have a Beta funciton that's so good that there's a month long waiting list for an invitiation). Also I don't think you can schedule tweets yet, and I get the feeling this is another Socialite-type app
4. Reeder - this is a Google Reader Desktop (and iPhone) app which I think I might try to alleviate the Google Reader part of my problem. I was hoping for one magic app to solve everything, but I don't think it exists.

Anyway, all of that was a very long winded way of asking you what you use to manage your social networking/online presence/Twitter existence. Help! Please? Any thoughts, opinions or application suggestions are very much welcomed by this computer-illiterate technophobe who wants to be able to perform social networking marvels.
